Our del Sol Leg Coolers are perfect for hot, sunny outdoor activities. Covering from ankle to upper thigh without bulk, our unique leg Coolers are made from ultralightweight non-chemical UPF 50+ UV protection (the highest possible rating) that won't wash out, sweat off or rub off. Plus moisture management to wick away perspiration and keep you comfortable. Made from great-feeling wicking, breathable fabrics with anti-microbial/anti-odor and resilient spandex stretch that won't impede movement, or get baggy during your activities. Our customers tell us they are cooler than not wearing anything! Available in unisex sizes XS through XL. Machine washable. Sold in pairs (these are not tights - one leg cooler for each leg).
