These deluxe covers have all the extra features knowledgeable owners look for, including zippered gas openings, vinyl-coated hooks, elastic base and adjustable straps. We’ve also included a special Expandable Windshield Cover feature for a custom windshield fit. A durable Lycra® elastic outer cover keeps any excess fabric tight and protected from wind damage. So, no matter what windshield you have on your Yamaha Snowmobile, you’ll get a clean, tight fit. Covers are made from a premium Sur Last® polyester fabric. It fights fading and protects your sled from the elements. A special urethane coating lets moisture escape from underneath, while remaining water-repellent. Soft polyester undercover helps protect your sled’s finish.
