This is a fabulous sling that is ultra-lightweight and can be used in the water! This is great for showers, pool time in the deep end with the big kids, hanging out at the beach and hot summers! This sling is made of Solarweave fabric. Solarweave is a revolutionary sun protection fabric! All Solarweave (SPF®) fabrics are UV tested and rated according to U.S standards (the world’s most rigid), which include 40 home launderings (wash and dry), 100 hours of continuous UV exposure and testing throughout the entire UVB and UVA range using precision electronic equipment. What that means is that SPF® fabrics effectively block at least 97% of UV during the equivalent of two years of normal wear and tear.
