I use mine under my helmet to help keep sweat out of the helmet padding plus the helmet slides on and off easier. It has held up well after lot's of rides and washings!

Great product idea and an excellent choice if your helmet is a little on the loose side. On long rides, my helmet felt too tight when I'd wear the beanine. Measure your head with the beanie on before buying a new helmet!
I've worn and washed my Zan vented head wrap a few times and so far it's holding up fine.
It's very comfortable in my Fox V2 helmet and helps keep the sweat out of my eyes. I like! I'll have to get another one in a different color.
