420D Jet Ski Cover 3 Seater 121-135 in, PWC Cover Fits Waverunner

Key features

• 420D Nano-Coated Fabric – 12000mm Waterproof Protection Built from extra-thick 420D Oxford fabric with a 6-layer Nano coating inside, this 3 seater jet ski cover has a smooth inner layer that won't scratch your PWC finish. Double-needle stitching at every seam plus sealed waterproof strips delivers 12000mm water pressure resistance, keeping your jet ski dry through rain and snow. SPF 85+ UV protection shields the seat and hull from sun fading. In long-term sun exposure, check the coating surface each season and replace the cover when the fabric shows visible aging.
• 4 Windproof Buckles – Stays Put in Storms & Strong Gusts Four adjustable elastic windproof buckles at the front, middle, and rear lock this PWC cover down tight in stormy weather and strong gusts. The full elastic hem hugs your jet ski body to reduce wind lift, while the "FRONT" marking makes installation foolproof. Shields your watercraft from rain, UV, dust, scratches, bird droppings, fallen leaves, and tree sap.
• Dual Air Vents + Elastic Hem – Snug Fit, Dry Seat All Year Two air vents on both sides keep air moving inside the cover, so moisture from rain, snow melt, and temperature swings escapes instead of collecting on your seat. That airflow keeps the seat and hull dry through winter storage and summer heat alike. The full elastic hem pulls the cover tight around your jet ski for a custom-like fit, minimizing flapping and water pooling. Four flexible straps connect to the windproof buckles for extra security during transport. Note: For boats with unusual shapes or side wings, slight water pooling may occur — tilt the rear or use a support pole.
• Built for Highway Trailering – 420D Tested Fabric This jet ski cover is made for outdoor storage and regular highway trailering. The 420D fabric has been tested to hold up under normal highway wind pressure without tearing — it is not built for racing or extreme high-speed towing. Four windproof buckles and four flexible straps keep the cover locked down while you tow, and the full elastic hem reduces lift at speed. A portable storage bag is included for folding and compact storage when not in use. Material: polyester fabric, not fireproof. Keep away from open flames and heaters, and let the engine cool before covering.
• Universal Fit 121-135 in – Measure Before You Order Designed to fit most 3 seater jet ski models 121-135 inches long, compatible with Sea-Doo, Kawasaki, Yamaha, Honda, GTX, Waverunner, and Polaris. This cover fits PWC widths up to 50 in — measure your hull width and total length before ordering, and leave 2-4 in of extra room for easy installation. Standard-height handlebars fit fine; if you have raised handlebars or added accessories like mirrors or a rear platform, measure total height first. To clean: rinse with a garden hose or wipe with a damp cloth. Do not machine wash — hand wash only to preserve the Nano coating.
