Geyoga4 Pieces Cooling Skull Cap Helmet Liner Sweat Wicking Running Beanie Head Wrap Cycling Bandana for Men Women

Thick band that feels snug. Lightweight material, great for under a helmet. Great price

Happy with fit and quality recommend to others

Given as a Christmas gift so I am not sure of comfort but he liked them.

It should advertise as "One size fits most"....a very large head may be too tight.

I was looking for a decently priced skull cap, and these are. However despite the multitude of reviews that claim these are comfrotable to wear under a helmet, they are not. The elastic band is way thicker than the rest of the skull cap. When you tighten the fit on the helmet, the thick elastic band makes for an uncomfortable wear. I gotta admit the fabric is quality, and the designs are cool, but that is a design flaw.

No issues after alternating these for a month now. I would wear these under my bike helmet. Defiantly works great on keeping the sweat off your face.

works well even during the winter

Not terrible but not great either. Gets rather uncomfortable after about an hour. Idk might just need I have a big head.
