Slastix® Technology was developed and patented by Stroops® back in the mid 1990’s for the safety and comfort of fitness and sport.  Stroops® is the original designer and manufacture of this MADE IN AMERICA product.  The patented design has proven to be much more than just safety and comfort alone. The sleeve protects the band from nicks and cuts, harmful UV rays and over-stretching, which are the leading causes of short life of the band, wear & tear and most commonly known injuries.
