Top quality gripper seat cover material with molded Stompgrip traction panels sewn-in on the sides. The Stompgrip traction panels line up with Stompgrip*s tank shroud kits and airbox/side panel kits where a riders knees grip when standing. They have proven to give the ultimate traction control for jumping and the whoops, as well as in turns when the bike is leaned over and the rider is sitting off the seat edge. The most durable cover available to deal with knee-brace wear. Made in the USA!
