Nanook Snowmobile Covers are top of class universal covers designed for all sled chassis and made to handle anything Canadian winters can throw at you. Our heavy duty TuffTex treated polyester fabric is rugged and resistant to rain, snow and ice. High stress areas are reinforced and all seams are double stitched for long lasting durability. Our multi tie down system allows option for storage and for trailering. The first set of straps ties the cover to the sled securely. The second set (removable) allows tethering to trailer or chassis for extra secure tie down. A soft inner layer protects the windshield area. Key features include a gas tank access hatch, rear air vents and rear reflector. A storage bag is also included. X-Long size cover fits x-long track sleds with chassis length up to 142".
