thank you for this brief overview. One more pro for down: the synthetic bags loose more insulation during washing than down bags. For winter you can use a combination of 2bags: a down quilt inside and a wide synthetic bag outside. The mostire will then condensate inside the outer synthetic bag. Using 2mats is also good for winter: a foam mat under the tent and a inflatable inside the tent, cosy and warm...
Great material 😊 You presented the differences between a down sleeping bag and a synthetic one in an interesting way. Giving the comfort of temperatures to the weight of the sleeping bag.
Ahhhhh ya like me in winter camps kayak or cycling tours even in snow in Ireland I’m all about the down mummy sleeping bag 650 using a down jacket with hoodie which together works great. And I use a cheap air mattress that always does the job inside my waterproof bivvi which I only use in wintertimes to keep me warm and sleeping bag warm. Ps well done on a nice clear film.
I use less insulation in my sleeping bag by focusing on the fill power. For example, a 650-fill power bag might require around 1 kg of insulation to keep me comfortable at 0°F. But with a 900-fill power bag, I only need about 700 grams of insulation to achieve the same warmth. This higher fill power provides equivalent warmth with less weight. The downside is that 900-fill power down takes longer to recover after getting wet compared to lower fill powers. While it offers excellent warmth-to-weight, it’s more delicate and can be slower to regain loft if damp, making it less ideal for consistently wet conditions.
I use a backless Tyvek thin quilt cover over my quilt, breathable to a degree (but no breathable membrane is perfect), but very light and compact, adds extra warmth as it’s an extra outer layer and doesn't matter if the Tyvek touches the wall of a single wall tent. As it adds extra warmth, I can use a lighter weight quilt. Tyvek is the vapour permeable membrane that they rap houses up in, but I use a thinner, lighter grade for my quilt cover. You can also get more enclosed Tyvek bivi bags.
I have been thinking about it as I always feel cold from the top, or maybe moisture lands on my sleeping bag. I do also lots of winter camping all the time. So a big footbox and cover from Tyvec will maybe help.
Good bottle for warmer bed are the Platypus plastic, one for the upper 1 for the feet. I have used them hundred nights. Never fail. And the 2 liters will keep you toasty. 1 liter is about the equivalent watt energy of a human body so having 1 liter warm water with you is good !
I use a special winter expedition 800 fill goose down sleeping bag in the snow and rain without a tent or bivvy. Warm and dry in all weather conditions.
If your zipper is not well sealed and insulated, turn the bag 90 degrees so that the zipper is on top and the insulation can be folded over the zipper. Having the zipper away from your elbows and side will make it feel warmer. It also allows you to adjust the temperature by allowing you to to open the zipper to allow some heat and humidity to escape.
If you use air pad & foam matt combo, put the foam matt on top! Even if the air pad has higher R-value. Dont believe me? Put them side by side, one hand on the matt, and one on the air pad...you will feel warmth from the foam matt faster.
I once put the foam pad inside the down sleeping bag. It reflected the heat quite well. Also, it folded around the feet not allowing that area to collapse. I did this one night in despair because too much cold was coming from the bottom.
@@FDijk You're so pathetic! 🙄 Of course a down bag is not dangerous! 😂 In fact a good quality 🦆/🪿 down sleeping bag is the safest barrier against winter ❄️ cold anywhere in the world. My main winter goose down sleeping bag is also fully breathable & waterproof with taped seams.
Awesome video, as always.
thanks Brat!
I love your videos man, you inspired me do bike for 3 months in East Africa

The darkness creeping in as the video concludes is a stroke of genius ^^
Well spoken for Dunn.

That is well made, informative video!

for one night sure
@mikkol79 No, all winter ❄️🥶.
Do you have a link?

Not if you use a goose🪿down air mattress such as the Exped.

@@Globetrotter-1 ah, true. I have not own a down pad.
think synthetic sleeping bags would be for me just because the expense of down ones.
🤙👍👍👍
Why does the Aerial bag come in red ? 😄 why not a color that is bis so bright
Do not like the bag... if i could go winter with quilt but makes sense what you say
I told mine she had to leave 😂.
*"where possible sleep off the ground"* is tip one😊😊
Down sleeping bags are cruel.
Nonsense! 😂
And dangerous cause they're useless when they get wet
