5mm Neoprene pads secure the lifting strap in the proper position while providing maximum cushioning during lifting. 11.5 strap is made from heavy duty nylon and Dura-Grip rubber for added strength. When using the strap, the rubber side must always face the bar. Dura-Grip rubber strips grab the bar for a no-slip grip when lifting. Heavy duty stitching strengthens the strap and increases durability. Designed with a right and a left. Steel buckle should be worn on the outside of the wrist. Fully adjustable, one size fits all.
