Add power to your strength with SPRI’s line of Braided Tubing. Rubber resistance is redefined. SPRI has braided four tubes together to bring you the ultimate dynamic full-body workout tools. Use the SPRI braided tubing indoors or out, wrap them around, under, over. They’re tough enough to take whatever you throw at them. The Braided Xertube offers all over the versatility of the Original Xertube and with its braided rope-like construction it is the toughest tube on the market. Built to a professional grade quality and designed for commercial gyms and clubs to be used 100 times a day versus 100 times a year in a home gym. SPRI rubber resistance products are created using a 'dipped process' rather than the more common and inexpensive 'extruded process' - making it one of the most durable and reliable tubes on the market! The handle plug, protective sleeve and grommet reinforcement features (Tuff Sleeve) also contribute to making SPRI the tubing product that is tough and reliable enough for many of the US military training kits. All SPRI rubber resistance products are made using Tuff Tube, a SPRI exclusive. This heavy-duty, high quality material has greater resistance to abrasion and tears to stand up to the rigorous demands of professional use. Built to a professional grade quality and designed for commercial gyms and clubs to be used 100 times a day versus 100 times a year in a home gym. Perfect for use in group training and strength-conditioning classes, Pilates and physical therapy and rehabilitation.
