Skinz Protective Gear’s Snowmobile Covers are stretch-to-fit, waterproof covers. They are unlike anything else in the industry. The construction of the cover make it entirely waterproof, except for a panel just behind the windshield and over the seat that allow for air to flow through while trailering. The materials will prevent salt and slush from getting in your sled’s cracks and crevices. All covers are machine washable. Please note that these covers are for trailering purposes only, not storage.
