Doesn't matter as the S'well will keep water colder, with or without ice. My nieces use Hydro Flask while I use S'well. I put ice into the my S'well and placed it into my hot garage for 24½ hours. It went from 32.5º to 32.7º in a sweltering 90.7º garage. Even without ice, I've left my S'well inside my car for 12 - 30 hours and when I drink from it, it's still just as cold as when I left it. The difference is the 25 oz S'well bottles are triple vacuum sealed while the smaller 17 or 9 oz are doubled. According to S'well, the 25 oz supposedly can keep water cold for up to 54 hours and hot for 26 hours. Haven't tested the hot as I'm not a fan of super hot coffee.
the hydro flask coffee cap isn't insulated that could be why it doesn't keep cold water as cold without ice.

I love my hydroflask
That's not a wide mouth and most people use that size for coffee.
