All bands include a Neoprene Functional Sleeve pair per band for nonslip, non-tear, and non-hair/skin pull during athletic moves where other bands fail and roll. Rubber bands are constructed with our layered, looped, and natural rubber from a Southeast Asian farm designed to be sheathed within our protective nylon sleeves for optimal performance. Each set of two Sleeves has the Sommer Ray logo on one sleeve and the tension rating on the other. Patent Pending.
