Go-sport 3 Pack Cooling Skull Cap Helmet Liner Sweat Wicking Cycling Running Hat for Men Women, Black+grey+navy, Medium

All three fit exactly the same. The fit is snug, without a giant elastic band cutting into your forehead. I'll be using these on my cycle as well as under my hockey helmet.

Slightly large for my average-sized noggin- just as far as coming over the ears a bit. Well made and good colors.

Husband has a brain tumor and has to keep his head shaved for treatment. This keeps his head cool and covered. It makes him feel more confident and doesn’t look bad at all. He wears it over his Optune device

Nicely made caps for under baseball cap and motorcylce helmet (my use). Size fits and for me a bit extra at the top as I do not wear over my ears until cold weather (wear it solo). BUT the seams press on the forehead with helmets and caps on....very uncomfortable after awhile. Too many seams which seem more style than function. Again, great cap.
