The stretchy performance knit fabric and contoured design makes for a snug, comfortable fit on most head sizes. This skull wrap is rated to UPF 50+ for protection against the sun's harmful UV rays and features an anti-odor treatment for fresh all-day wear. A reflective accent enhances visibility in low-light conditions. The low-profile design fits comfortably under a hard hat or helmet and is a great option for those with longer hair/ponytails. Ideal for construction, landscaping, roofing or anyone working in the heat. It can also be used to reduce the risk of heat stress for outdoor recreational activities. HOW TO ACTIVATE Just soak in water until saturated, then wring out excess water”the evaporative cooling process begins instantly and lasts for hours when worn in environments with suitable airflow.

Review: Cooling effect is surprisingly great! - Its a bit heavy but it feels soooo good. It's thick and keeps your head cool for much longer than I anticipated. It fits a bit tight, but that's okay because it stays on, but it can become a little uncomfortable after a while, but you get used to it. It doesn't look great when you're wearing it, but who cares when you need it to stay cool or have a headache. I do love that its large enough you can pull it down over your eyes, incredibly helpful for a migraine. Made from a good quality material too.

Great item to keep sweat of your face and glasses. Soaks up so much sweat that I was surprised by just how much sweat a had to wring out after using it. Never felt hot. Always felt cool on my head.

### ⭐⭐⭐⭐ Good quality and comfortable
*by J***M on August 10, 2025*

These are comfortable. I would have given them a 5 star, but it seems that they dry out too quick after I wet them to keep me cool. I use them whenever I go walking.
