Sand-Free Life in Sand-Filled Paradise – CGEAR's Sandlite series features quality construction and the only patented sand-free technology on the market to offer versatile, cutting-edge comfort. Patented Two-Layer System – Sandlite's secret is a precisely engineered system of polyester layers that allow sand, dirt, and dust to fall through the fabric without being able to come back up. Perfect For Everything Outdoors – In addition to sunning on the beach, Sandlite mats are great for stretching and exercising, picnicking, camping, backpacking, and protecting important equipment. Durable For Repeated Use – CGEAR technology was originally developed for the military, and though our products see more vacations than battlefields, they're still made to withstand a lifetime of rugged use. Sized To Your Needs – SMALL offers plenty of room for one person. MEDIUM is great for couples. LARGE accommodates up to four people. All mats roll to a compact size and feature a carrying handle.
