Evolution Athletics Wrist Wraps are offered in two length sizes – 20” and 30” to choose the best length for your wrist size or for the weight being lifted. The Evolution Wrist Wraps, professionally designed by 4X World’s Strongest Man, Brian Shaw, are the first of their kind to provide both a thumb loop and belt loop in the same pair of wraps. These Wrist Wraps provide additional wrist support and stability for all pressing and overhead exercises. Flexible wrap is easy to lock down and wrap around your wrist. Two large velcro pads are split to provide a large area to cinch up for custom fit. Velco closure includes a firm backing for added support and retains a professional appearance. Both the thumb and belt loop material is extra durable and resists breaking down or stretching out over time. Sold in pairs.
