Eh. I mean, it was warm… but it trapped moisture from me breathing into it, so then it was like wet… which wasn’t ideal. Didn’t stay up on my nose super well. I had to tuck it into my goggles. Easy to wash. Decently soft. Feel like it wasn’t exactly worth the money I spent, but I know it is real wool, so that comes with a price tag. I don’t know…I really didn’t like the water / moisture getting trapped around my mouth and chin and what not. Just causing skin breakout issues. Helped cut the cold wind, but I feel like it could be better, or like there are better options out there maybe. Maybe not meant for snowboarding or exercising, so you’re not breathing as hard into it. Maybe it’s just meant for walking around with it around your neck. I don’t know.
