The 4″ Prowler loop is the state of the art for serious athletic training. This 16′ loop is durable and washable. It features an extra-wide webbing designed to provide comfortable, safe anchoring across the body at higher resistances. This loop has 8 feet of stretch before hitting a soft end range. This soft end range is a significant safety and comfort improvement over the hard end ranges experienced with covered rubber bands. This piece is also very comfortable to grip and offers up to 85 LBS of resistance in each hand when anchored at the midpoint.
