While I loved this video, please do not make a similar one on flame-resistant garments. Just saying.
'For science!' WhOOOsh 🔥
As a fire performer, PLEASE make one on flame resistant garments! We need it 😅
I would love to see how this compares to like merino wool, alpaca, etc. So many anecdotal claims, but a more "scientific" approach would be nice.
You can't. That's how they get away with all the claims. Anytime you see ANY comparative word like 'warmer', dries 'faster' etc you have to ask, "compared to what?". And they will always be comparing to the worst full synthetic garment ever made.
Nothing with any amount of synthetic material can compare to even the lowest quality natural fibre.
@@WeatherManToBe haha good synthetic material can definitely hold up to a poorly put-together piece of clothing made of natural fibre.
@@WeatherManToBe I agree that synthetic is widely used in things it shouldn't be used for because it's cheaper and that it isn't great for the environment. It's important to note things like gore-tex are more windproof and waterproof. If you are a artic explorer, astronaut, or deep sea diver you are going to be in synthetic material because it can be made with properties that natural does not possesses. Now in regular peoples lives probably all you need is a synthetic umbrella at most.
i have heat tech pieces from 10 years ago. they were good but i started wearing shrunken Uniqlo merino wool and cashmere sweaters from about the same time period as base layers and i gotta say heat tech sucks in comparison. the problem with heat tech is it doesnt handle sweat as well. maybe it doesnt breathe as well, or absorb moisture as well, i dunno but im not into heat tech anymore since then.
i watched a video about the US military's system for cold-weather clothing and according to them the number one issue ended up being dealing with sweat. your sweat must evaporate or else you're gonna get cold. kinda hard when you're trying to keep warmth in, right? iono but that logic seems to check out in my experience; i have some airsm t shirts that dont breathe at all but also an arism hoodie that i can wear in 90 degree weather, so i know polyester CAN be breathable. i think the upside to wool and cashmere is their ability to hold huge amounts of moisture without feeling wet.
I live in Nunavut, I have their Merino wool sweater and it is warm. Plus heat tech. It makes a difference. Now a caveat, you can put layers of anything and it will be warm, sure. But this does allow for me to be warm while being lightweight.
Love this, you’re doing what a lot of fashion RUclipsrs aren’t
Ridiculously good quality. The sub has been worth it
I live with Multiple Sclerosis, very temperature sensitive. Love heat tech and airism products from UNIQLO. Easy to layer to deal with climate change. Outstanding review!
Love the scientific test!
I do winter hiking. To stay warm, it's best to use the 3-layer system.
Base layer: Polyester to wick away sweat
Mid-layer: Insulation layer that actually keep you warm, cashmere, wool or fleece
Top layer: Block the elements.
I think Uniqlo Heattech Ultra heat is an affordable option for mid-layer. IMO, it's a bit overkill as a base layer. You'd get too warm when you get indoors.
interesting! i do that too but tend to use the heattech as a base layer since its usually a tighter fit. When using ultra heat as a mid layer, what do you prefer to use as a base layer?
Wow, you guys really are doing the most, I never expected this level of testing and production quality! Interesting to know a CLO is based on 1940’s suit, that makes a lot of sense with how cold I still feel despite the heat ratings.
I love my heattech base layers. Best purchase I’ve made and lasts a long time. Makes a huge difference in reducing bulk in the winter
The thinner one is part of my daily uniform for under my scrubs. It is a bit chilly in a hospital. Also when I travel it is a lightweight effective base layer
I love this channel. You’ve cost me money, instead of shopping for clothes at Costco & Sam’s Club, now shopping at Lulu & Uniq. I am waiting on my Thursday sneakers to come in; feeling like a cool kid agin 😂. thank you for the quality breakdowns, helps us that insist on value. thank you
Same here!
It would be great to include a moisture component. As something could be warmer but not as breathable causing you to be colder in the long term.
More than the actual test itself, the thinking that goes into these tests is fascinating.
I'd have just tested these garments one-by-one, instead of cutting them into two and sewing them together for a head-to-head comparison in the same conditions.
And then thinking of a walk-in freezer as a possible refinement to get a more consistent test environment when the weather proved too inconsistent.
The results were interesting, but the problem-solving during experiment design? That's my jam right there.
loving where this is going! would be interested in learning how long the anti microbial treatments last in something like this and whether it's more or less effective than using something like merino wool to combat odor over repeated wears.
These videos are always awesome but this one went above and beyond. Super impressed, will always say that you guys should be way more popular.
For a potential Behind the Tech video idea, it would be cool to see something for the outdoorsy crowd, who certainly put a lot more emphasis on the scientific and tested merits of their materials compared to the average consumer.
One specific idea would be the difference in performance between a GORE-TEX garment and a PFAS-free alternative to GORE-TEX PRO like Patagonia's H2No. It's a very relevant topic and I'd personally love to see this.
Thanks for the suggestion! Patagonia claims their H₂No garments are "made without intentionally added PFAS", which seems to imply that there may be some level of PFAS in their garments even if they don't directly add any. It would be interesting to not only compare if the addition of PFAS is necessary for weather resistance, but also is there is actually any PFAS present in Patagonia's garments.
This video was great! Good information, clean video great edits, not a lot of bs you've earned a new subscription!
In terms of experiment design, now you have to redo this test WITHOUT cutting the fabric. Do first one separately, and then another one separately. Since by cutting it you basically reduce the properties of the better fabric, since now you are “leaking” heat from the “weak side”. Thats why you experiemnt cant prove or deny the 2.5 times claim, it is not a clean experiment. But all this just to nerd out completelt 😂 Otherwise excellent video! Can’t wait to see more of your experiment!
Thanks for the suggestion!
We opted to seam the two shirts together rather than testing them separately as the fluctuations in outdoor temperature between tests may also have had an effect on the data. Hence, we did our best to find a good balance of having both a decent comparison of the two garments and something that would be visually interesting for this first test.
Going forward, we’re looking to find a more consistent environment like a walk-in freezer to do these kinds of tests, as this would allow us to do more objective comparisons than we can do using the outdoors as our test environment. We’re also working on designing a more consistent temperature source that we can use for all of our tests, as we want to make sure that we have much more repeatable testing conditions before we begin to rate things (as we do in our Industry Secrets series).

@Shiftfashiongroup thank you for such a detailed reply 🤍
True, I thought the same
Doing the hard hitting investigative journalism that will heal this broken broken world!
We used heattech (thin) during our summer holidays in Iceland (camping). Comparing to woolen undergarments it was a much more economical option and we were very satisfied with the heattech t-shirts and leggings- thin and comfortable, great for layering. I like their ballet neckline (i think it’s what they call it) which is perfect for mild winter layering for indoor use.
Absolutely taking huge steps in improved the quality of your videos even more.
With regards to heat loss, the subject wearing the fabric is also a variable - full or empty stomach, tiredness, … maybe doing a test on a dummy might give the most “clean” results that ofc don’t consider the water vapor loss of the human body.
Lovved how detailed you guys went with this. I actually bought both of these last month.
For the price these are great. I use them both in the winter
Great testing! No one else is doing this! If i may, I'd like to make a suggestion for your next video, as I've always wondered, is it better to wear 2 layers of thin heattech rather than 1 layer of Ultra warm heattech? Because when it comes to hiking, I want to go as light as possible so if 2 layers of thin heattech is as good as 1 ultrawarm , I'd rather bring 2 thin heattechs, its just gives me more options to adjust to the weather and even allows me to wash 1 and wear the other. Weight wise both options seem to be fairly close, that's why this is a legit consideration.
My wife and I love these shirts. We found them amazing (especially the ultra warm) when we were in Disney in the December. Great base layer if you're going to be outside for extended periods (theme parks, sporting events).
For me, the regular Heat Tech is perfect under a hoodie on cold days in our relatively mild, southern climate.
This is awesome. Put Toronto on the map!
I am a big fan too! I appreciate this channel and the work they are doing. i am a hobbyist tailor and interested in the way garments are constructed. The work on this channel is always detailed, timely, interesting and useful. Keep up the good work, guys!!
You can do room temperature meat in a garment in a freezer for consistent measuring. You could use a wireless meat thermometer to plot heat loss
Love the new production value on this series! Would love to see more testing on outdoor wear or active wear expensive vs affordable brands
I use Heat Tech ultra warm as a base layer (shirt and pants) while motorcycling (down to 5°C) and I am pretty happy with it. Granted, I have no other dedicated base layer to compare it to, but compared to a cotton shirt and nothing underneath my riding jeans, it is a noticeable difference. I'm comfortable for around an hour of riding before I look for a spot to warm up.
Great video! Love that you’re testing claims from the manufacturer- this one seemed to come close to their claims. ❤❤❤❤❤
I had some heattech socks I bought in Shanghai in 2015. I have to say, they did not only did a great job, keeping my feet warm AND dry. They were not even thick, but waffled on a very small scale. Then, they were off supreme quality. I had them for around 7 years. Worn a lot during the colder times here in germany, so around 5-6 month.
Oh I wear these in the black version for work! They definitely last a long while, and keep the heat in in cold temperatures. My work uniform is just a thin black shirt and winter mornings get really bad without this layer, I do agree it gets unbearable the closer it gets to 15-20c degrees though.
Really appreciate all your hard work! Just here to add that Heat Tech gets warmer if you sweat in it, because it supposedly converts vapor into heat. So an idea could be to try doing some activities with varying intensity to try out how warm the normal vs ultra one gets!
This is really cool, thank you! I think the walk in freezer is a good idea. I want to buy some thermals for my dad who is always cold in the office building, and i think the regular heattech might be good for him
Really enjoyed this and how you made the shirt to ensure same testing conditions!
One possible way to measure more consistently would be to have an insulated box that you separate in half with the fabric you're testing. One half would contain a heat source and the other would just be at ambient temperature. You could then measure the temperature differential on both sides of the fabric, as well as the heat transfer over time. You could use this test apparatus inside of a climate-controlled chamber as well. Great video
Thank you; we're actually working on building this exact thing to use for our testing going forward!
There’s also the Heattech Extra Warm which is a middle point between these two, it might be the best of both worlds
Great video. Thanks. I will like to see you continue this test.
Me living in Texas, being cold at 68 degrees 😅
Really interesting test! I feel for you sitting on that metal chair in the freezing cold - and no sun makes a surprising difference! Brrrr!!
Nice test. Adding an infrared thermal camera might be worth considering. There are some USB models that plug into a phone and aren't too expensive.
I’m more curious how does the heat tech (thicker version) compare to cashmere, merino wool or other winter undershirts
I’d like to see two different tests with one garment at a time. It was neat seeing both attached as one piece. What is the most comfortable to wear for indoor and outdoors for daily use?
Thank you for sharing so much garment knowledge to regular consumers like us. I've been researching about garments and materials myself just out of curiosity and thank you for stating why certain materials are used in garments and especially shedding light on what would be a more sustainable purchase for consumers like us.
I would love to see segments or interviews with manufacturers explaining how they're able to manufacture such volumes. why pick certain materials and lastly, what is the future trend we need to expect from clothing industries? Are we moving or starting to move in a sustainable direction or are we regressing in terms of fabric technology?
Awesome video! I love that you are doing objective tests. I don't know any other RUclipsrs doing this kind of work. A suggestion for future measurements for your last graph (showing Outside Base Layer temp): The base layer prevents heat from reaching the temperature probe, so temperatures measured this way will be lower than without a base layer. You can do two tests sequentially: one with the base layer and one without.
Thanks for the suggestion and glad you enjoyed the video! We opted not to do a control since the outdoor temperature was fluctuating enough throughout the day that it would be difficult to easily repeat the test. We're working on designing a new heat source that we can use going forward which doesn't require throwing Joe out in the cold and will make it easier to do control testing and directly compare garments, even across multiple videos.
I greatly appreciate the effort man... Thanks
Look here is what you do. You take two boxes made of any material, let's say plastic. In each box you put boiling water and a thermometer that you can read in real time (lot's of cheap options online). You insulate one box with the cloth from one type and the other with cloth from the other type you're testing. You put them out in same environment next to eachother. The difference in time it takes for the water to reach the temperature of the outside environment is a direct indicator of the ability of the two types of cloth to insulate. If you really want to take the measurement to the extreme you in insulate the boxes with like 4, 5 or even 6 layers of the same material. This way the temperature drop will be much slower and you'll able to see smaller differences between the two matierials.
You're welcome.
I’m loving this!! I want to break down more tech! 🎉
I feel like you’re gatekeeping some great brands from us! I’m sure you have your favorite tee, favorite pants, favorite jacket! You wear T-shirts that I want, great collar, great fit, great length, etc. Stop the gatekeeping!
Joe - haha I actually don't. Each brand will use multiple suppliers. So some items are good and some are bad. For example I like stone island jackets, but I have have had pants and shirts from them that are not worth the price. That's why I don't really want to give a brand a over all gold seal without exploring their entire product offering. Because I know that will be a disservice to our audience. A brand will not get my recognition without deserving it. As for the shirt. We are working on a project that that shirt is a part of. Stay tuned 🙏
Thanks for the thoughtful reply!
I’d be interested to see you compare Heat Tech with GU’s Style Heat. If you’re unfamiliar with GU, it’s owned by the same parent company as Uniqlo and you can think of it as Uniqlo on a budget. They sell very similar products to Heat Tech called Style Heat for a bit cheaper than Heat Tech and I’ve wondered if they’re basically the same product under another name.
Would love to see a review about Columbia Omni-Heat Infinity base layer and comparing it to this one to which one is preserving more warmth
omg i freaking love your content! so helpful!
I never feel cold other than walking to/from the car to the destination (mostly
actually, maybe a fleece seat cover will do.
Why not wrap the fabric around something like a warm water bottle or something? Then you can standardize the starting temperature, remove any noise from the shiver response, and also not be miserable in the cold.
I dont want to be "that guy" but you can't compare degrees celsius and say its 2x warmer, because celsius (and farenheit for that matter) is basically an arbitary scale. But a great start and an interesting experiment!
Woulda been good to plot the actual temps in Celsius rather than just the difference in Celsius. Yes they could just report the difference in Kelvin and be fine, but most people don't know how Kelvin works. If they had the absolute temps in Celsius, people that are turbo geek enough to care could pause and do the math in Kelvin ourselves
Thanks for doing this
Thank you for sharing your knowledge with us. What are your thoughts on Icebreaker? Is it the best merino wool baselayer with affordable price? How does it compared to other brand's merino wool baselayer?
Watching this and a Uniqlo ad shows up 😂
Love the content!
Great, now I want them both!
Great video! This is something I always wanted to know!
Hi! Could you do a comparison between Uniqlo clothing quality and their sister brand GU? The GU is slightly cheaper with some items like the puffer jackets way less expensive. I would love to know if the increased cost was worth it for most items. Thanks!
Amazing videos!! Curious how it compares to regular cotton long sleeve, wonder if base layer is just a hype
I can just answer that. Cotton will absolutely make you colder than a more technical fabric or wool. This is because of the cooling effect cotton has. Because it does not dry quickly thus any amount of moisture stays in contact with you longer cooling you off. In terms of performance your really looking for a fast drying and high wicking material. Warmth is less of a interest when thinking about a base layer for sport or performance activities.
Love heatech and airism. Good bang for the buck
This was a good quality video. Commenting for the algo
i would prefer if you do this test over two separate days in a giant freezer. also, maybe put the probe at the armpit area instead?
how longjohns are supposed to work is to create a tight fit -- not allowing any air in. cutting them up and stitching them does seem to have allowed some air to go in via the seams....
Would you compare other brands that offer baselayer in different warmth and see if their claims are true?
Would love for you to test ice break merino thermals to compare
Can you go over your favorite clothing brands
Well I'm curious to know what shoes were you wearing??
Please also do a Nike therma heat test as well
Can you do Isaia aquacashmere, Loro Piana green storm system, or Zegna's stratos? Aka waterproof cashmere.
I've seen a lot of complaints online about acrylic being the worst yarn possible for thermal purposes. Is it really that bad? Why then would Uniqlo pick that specifically for their base layers?
Comment caveat: I run pretty warm. Used to run and cycling in the winter
I have an Ultra Warm turtle neck and holy shiet I don’t know the use case for it
It’s too warm for winter unless you’re just standing around. Once you start moving it acts like a sweatsuit
The only way I think it can work is you wear a spring or fall jacket. No way that can be worn for any activity
20⁰C in my place is really cold.....different country different perception of heat
It would be great if you could do a deeper dive on OVO, I see you’ve just done a T-shirt thus far although the brand has hoodies and much more as I’m sure you know. I’m knee-deep in the brand so I need to know the truth!😂
It's definitely on the to do list! We are actually based in Toronto as well
I would also like to see a comparison between a 100% cotton, 100% wool shirt and the heattech shirts. Of course, fabric weight and cut have to be taken into account. My wife loves Uniqlo heat tech, but for me it doesn`t work. There is something about the shirts that makes me feel uncomfortable. I cannot exactly pinpoint what it is. Maybe the breathability is not as good as they claim. I have the subjective feeling that my body regulates heat better with a traditional wool or even cotton shirt.
Please do a review of Unbound Merino or comparison with other popular merino wool brands. Really want to know if it's worth the money. Thanks.
How does one wash these ?
What’s the brand of his shoes?
Can you review clothes from Saaltstudio next? Love your videos!
Awesome content!!! I subscribed!!! 🫰🏼
I miss you so much, I really want your shaker bottle back again T_T The Umoro
Hmm the problem I could see with that test, cutting into half and stitching together…..
One side might be looser and causing more heat to trap while the other might be overly stretched and hence surface cools off faster….
And depending on your heart rate at the moment, it might skewer the results……. If it does… just throwing it out
And these two types of shirt fit differently. I own both types and the ultra warm fits looser and more like a normal shirt, the normal heattech is very much just a base layer.
Speaking of Uniqlo, does their clothes fit Asian bodies better? I’m wondering if that is a general opinion among Asians or do they really have different ratios that are aimed at non-European body type.
comparing ralph lauren outfits to target, and see the worthiness these clothes are
Surely the best test would be to do two separate tests instead of chopping in half
Joe - Hard to control for the temperature variability as there has to be time to pass to warm up and re test. In future we'll find a walk in freezer company in the city to partner with to do this testing or use off body testing rigs
just subscribed 👍
Dang why's heattech more expensive in Canada than in the Philippines??
I first want to say that I appreciate what you’re doing. I want to show my appreciation by sharing some thoughts.
1. I live in Kansas and the temperature drops to below zero (Fahrenheit and Celsius) several times per year. Despite that fact, I didn’t know how to dress in layers until my late 30s when some friends from Minnesota were casually talking about it. Maybe there’s a role for you to be that friend that teaches how to stay warm.
2. I’ve embraced the concept of being comfortably cold when I plan to be outside for a long time to reduce the chances of sweating while in freezing conditions.
3. There are two main use cases when I plan to be in the cold. 1) going around town where I’ll only be outside and 5-10 minutes at a time and 2) being outside for 30 minutes or longer while doing something active like hiking or sledding. I’d want to know how the item would do in those two use cases.
4. Being able to regulate temperature is important to me and if that’s a feature in the item of clothing I’d want to know.
5. Knowing what temperature to use an item (I.e. conditions that the item was designed or intended for) is important.
6. Putting it all together: base layer, middle layer, outer layer.
7. Continue calling out comfort transitioning from cold to “normal” conditions (I.e. home or office) and vice versa.
If I can be of any additional help let me know.
The magic of Heat Tech is also that it's comfortable enough to wear at room temperature without sweating your balls off. 😄
Subbed 👍🏼
Dang it, just when its 1 am here Singapore… ah welll
leveled up
really? rayon is exothermic? It feels cool when it dries?
The moment you cut it in half you basically reduced the efficiency of the ultra Hi tech.
Ooof, can we pass on that music? Other wise, stellar job as always
32 cool next?
💜💜
Suppose I wore a heat-teach on top of an ultra heat-tech
So, Uni-Qlo might be using Celsius for saying 2.5 times warmer. However, 10 degrees C or even 10 degrees F is not twice as warm as 5 degrees. 10 degrees Kelvin (Kelvin starting at absolute zero) is twice as warm as 5 degrees K. 10 degrees C is 283 K which is barely different than 278 K (5 degrees C). I am not normally this pedantic, but you do seem interested in the science of fashion design and saying that a slightly heavier fabric is keeping you 2.5 times warmer is kind of meaningless when you consider the actual science of it.
Thanks for your comment! UNI-QLO states on their website that their 2.25x measurement is based on the garment's clo rating, rather than some kind of direct temperature measurement. 1 clo is the amount of insulation that is required to maintain thermal equilibrium in a normally ventilated room at 21ºC.
@@Shiftfashiongroup Thank you for the clarification. I got focused on temperature because that was the measurement you used. However, in fairness to you, you never suggested a numeric relation with your two sets of data.
Love your deep dives into quality and the qualities of fabric!
