Review on 🧢 GearTOP Skull Cap: Ultimate Sweat-Wicking Beanie for Men & Women - Ideal for Sports, Work & Outdoor Activities (Cool Black) by Jay Lee

Fits a small head very well. Added slightly more head size for a snug fit under the helmet. Should work as stated in the product description. Stays on head when helmet is removed. The quality is good and looks durable, should hold up to a wash. I would hand wash and air dry it. A bald head should be warmer than a cheap carpet. Didn't find it accumulated under the helmet. Avoid drafts and cold air. ride up!
