They Fit

I bought this and the flame pattern for my husband, who has a very large head. They fit, he loves them. It's a win-win for me.

This cap works as a sweatband in summer, and a light warming cover in winter.

Nice cap, long wait

I like the cap, looks cool, elastic holds it on well. I had to wait several weeks, though. Speed it up, guys.

I like the product...but I wish it had the elastic band in the back like other caps... previous experience the headband area stretches out after several washes & is loose on my head.

I really liked the material colors pictured identical to the pic posted the only small problem was that it's a bit loose it's tight because of the material, it would be like a stretch tight fit but it works for what it's worth.

Good, but not great
3 stars out of 5 stars
I've been using the Chill-Its doo rags for cycling and really like the quality. I figured I'd go with the cap for a cleaner look. The doo rag has a very nice elastic and terry around the edge. And although the cap has a nice terry sweat catcher around the edge, there is no elastic to grip your head. Therefore, the cap is a very loose fit. Overall, it's still a nice product.

Skull Cap
4 stars out of 5 stars
I like it a lot except that it comes in one size. I have a fairly good size head and it's a little loose on me. I would prefer it to be a bit tighter. Someone with a small head might be disappointed.

Great cap

Bought these for my husband to wear to work and he loves them. Not only do they keep the sweat out of his eyes but they keep the dirt out also. Didn't find that they were cooling in any way though.
