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.
Great item... 2 bucks more than the other head wraps, but the built in terry cloth (towel) sweat band is soooo worth it ... they fit large, as I wear XL or XXL helmets and these fit me really well. ... I am going to order more
