Review on 🚴 Cycling Cap - Reflective Bike Hat Under Helmet for Men & Women - Sun & Sweat-Blocking Bicycle Helmet Liner by Steve Guillen

Well maybe not if you have a very small head. I wear an XL hat and it's pretty comfortable. I've been using it for about 3 weeks and find it comfortable and light weight, allowing it to fit under my bike helmet without puffing it up. This would be great for running or aerobic exercise where you want the cap to fit snugly so it doesn't come off. Haven't washed it yet (3 weeks, uh uh) so can't comment on durability but I've been looking for a cap like this for a long time and highly recommend it!
