Polaris RZR Seat covers are made from 500 denier waterproof Nylon and use elastic around outer edge to attach under seat bottom and seat back. Neoprene side panels and heavy Velcro straps on back and sides of seat covers lock covers in place so they stay in position no matter how rough the trail gets. Seat cover offers great protection to factory seats with easy installation and no tools needed for a tight factory fit. Comes with all neccessary mounting items and instructions. Fits thru 2014 RZR. Made in USA by Greene Mountain Outdoors.
