These arm sleeves keep you dry during your toughest training sessions, thanks to adidas AEROREADY. Reflective logo details flash in low light, so you can workout in dim conditions. The cuffs stay put with silicone to keep them in place. This product is made with at least 70% recycled materials. By reusing materials that have already been created, we help to reduce waste and our reliance on finite resources and reduce the footprint of the products we make.
