I purchased this because I am a bicyclist and I do some late fall / early spring bike riding, often when it is skillcold outsite. My bike helmet is vented so my head gets cold, so I needed some type of cap to keep my head warm. And this worked PERFECTLY. If you go to a biking catalog or biking equipment website you will pay a lot for for a bike helmet liner. The material of this skull cap is very thin, but it still keeps my head warm. And most importantly, with the thin fabric it does not interfere with the fit of my bike helmet. There is some give in the fabric, so it shouldfit most heads. And it does not slide around on your head. It stays in place. There are two sections of the same fabric that tie in the back, so you can really adjust how tight it is by how tight you tie it. When riding with my bicycle helmet on, you don't notice the cap or feel the cap on your head. And my bike helmet still perfectly fits my head. When I remove my bike helmet, the cap is still in place -- it has not moved around on my head during the ride. Plus....gotta say..........when I remove my bike helmet after I ride, this cap looks pretty darn cool. I even bought a second one of these it worked so well.

I don't ride a bike I just wear it anytime I like, Perfect for bad hair days.There soft and comfortable to wear. I like wearing them so I own several pairs.

It fits well on my head and adjusts easily. It stayed on my head through the night which is surprising since I toss and turn a lot.

Soak it with water and keeps me cool on hot days in San Bernardino. I build BBQ Grills for Home Depot outside in the garden area, no AC outside, I use a pump spray to keep it damp in conjunction with a neck fan.

This was a gag purchase, it would be too hot for work.
