Dri-Technology consists of a proprietary combination of synthetic fabrics that give the SWEAT<LESS products, and all Dri-Accessories, their anti-microbial and hypoallergenic capabilities. This technology inhibits the growth of mold, bacteria and fungus that can penetrate your skin with less quality towels. The moisture wicking properties of our SWEAT<LESS fabric allows you to dry faster while eliminating odors and bacteria after every use. Regular fabrics, like cotton and microfiber, which many people use to absorb sweat, can maintain stains, odors, and dangerous bacteria like Methicillin-Resistant Staphylococcus Aureus (MRSA). MRSA can live on a cotton towel for up to 6 weeks! Think about that the next time you sweat!
