Review on 🧢 Men's Sweat-Wicking Cooling Skull Cap Helmet Liner - Beanie Cap for Biking, Cycling, and Motorcycling - Ideal for Motorcycle and Hard Hat Comfort by Mike Palma

Bought this for my dad. He is bald and being treated for skin cancer. He needed something more comfortable than a regular hat, with sun protection and a larger size. They are perfect for that. The upper is made of soft mesh and the sides are made of a very stretchy material (possibly poly/nylon). It's light and cool, and sweat doesn't seem to be dripping down his face. I can see how great it would be in a helmet. He wants more, so we look forward to stocking them.
