SRIMMIT's Jet Ski Waterproof Cover (121–135 in) is a heavy-duty, UV-resistant PWC cover designed to keep three-seat jet skis dry, scratch-free, and secure during storage or transport.
This all-weather cover pairs thick 420D oxford fabric with a six-layer nano coating to block rain, sun and abrasion while remaining soft against painted surfaces. Built-in vents, elastic hems, and four adjustable windproof buckles deliver a snug fit and reliable hold on trailers, docks, or driveways. The cover comes with a compact storage bag and clear front marking for quick orientation.
The cover uses a dense 420D oxford outer and six-layer nano-coated inner construction to resist water and UV radiation without leaving abrasive contact on gelcoat or paint. Double-needle seams plus waterproof tape increase seam strength and water resistance, while the soft interior prevents scratching.
SRIMMIT designed multiple retention systems to keep the cover secure in gusts and during transport. A full elastic hem hugs the hull while four adjustable straps clip to windproof buckles at front, middle and rear to resist uplift and shifting.
Two low-profile air vents on each side promote continuous airflow and help disperse trapped moisture and condensation, reducing frost and mildew risk. Proper ventilation helps keep seats and electronics drier during long-term outdoor storage.
This model is tailored for most three-seater personal watercraft in the 121–135 inch length range, including many popular Kawasaki, Yamaha and Honda PWC models. Always measure from bow tip to stern to confirm fit and leave a little slack for accessories like ski racks or tow bars.
Who is this for: Boat owners and rental operators who need a durable, weatherproof cover for three-seat jet skis that offers strong UV and water protection without scratching finishes. It's also suited for seasonal storage, marina or outdoor parking, and transport on trailers when a secure, vented cover is required.
Q: Is this cover fully waterproof?
A: Yes — the 420D oxford fabric with six-layer nano coating plus taped seams resists heavy rain up to 12,000 mm water pressure.
Q: Can I use this cover on a trailer during transport?
A: Yes — the full elastic hem and four adjustable windproof buckles secure the cover for trailer transport in typical conditions.
