These trick seat covers incorporate a side panel traction strip for ultimate control in most riding positions. The STOMPGRIP™ Traction Strip is made of a pliable elastomer material molded into shape with traction knobbies to provide a functional, non-abrasive grip to the side of your seat. The traction strip has been placed in such a way as to keep it out of the way in most seated positions, yet provide the necessary traction on the inside of your legs or on your knee when in an aggressive stand-up riding stance. Whether you are ditch banging, trail riding, boondocking, racing or hillclimbing, the added traction in this area gives you much greater control of your sled, as well as helps you save energy with less arm pump. It is amazing what you can make your sled do when you have your legs firmly planted where they belong.
