Great for underneath a ski helmet
I've had issues with overheating when downhill skiing to the point where my goggles fog and build up moisture which impacts my vision, and any beanie I wear was soaked at the end of the day. I'm bald, so a beanie is necessary to keep me from getting cold under my helmet. My sister found this one from DeSoto, and what a difference! I'm still plenty warm, but my goggles don't fog any longer, and at the end of the day I'm more comfortable because the beanie allowed the heat and moisture to wick away. It's also easy to dry when I take a break using a standard bathroom hand dryer, and it's easy to wash as well. I just ordered another one so I have a backup, but I highly recommend.
