CGEAR Our patented system is a precisely engineered weave that allows sand, dirt, and dust to fall through the fabric. Because the layers are staggered, sand can only go one way (down), not back up. And because this towel is made with 100% high-quality polyester, it’s super soft to the touch. Most towels are either quick drying or absorbent. Higher thread counts feel softer but are also woven more tightly together, which means they retain water for longer periods of time.By using our proprietary multiple-layer system, the Sand-Free Towel has double the air-surface exposure, making it twice as quick drying. Its large profile makes it a perfect beach blanket and it packs down to a small enough size to make it super portable. The towel also features a hanging loop so you can easily stow away the towel when you are not using it.
