SRIMMIT Jet Ski Cover 121–135 in – Silver/Black UV-Resistant Waterproof PWC Cover with Venting & Buckles

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.

How does this cover protect my jet ski from rain, sun and scratches?

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.

• Water resistance rated to withstand up to 12,000 mm water pressure
• UV protection with SPF-like blocking for prolonged sun exposure
• Soft inner layer that won’t abrade hull or seat surfaces
• Reinforced stitching and taped seams to reduce leak points

Will the cover stay put in windy or stormy weather?

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.

• Four elastic straps with adjustable buckles for firm anchoring
• Full elastic hem for a tailored, low-profile fit
• Front, middle, and rear buckle locations to distribute tension
• Marked "Front" label to speed proper installation

What features keep moisture and mildew from building up under the cover?

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.

• Dual side vents to encourage cross-ventilation
• Inner smooth layer that sheds water and dries faster
• Instructions included to let engine cool before covering to avoid trapped heat

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.

• Fits most 3-seat jet skis with overall length between 121–135 inches
• Compatible with trailered and dock-stored PWC setups
• Comes with storage bag for compact packing when not in use
• Measure your craft before ordering to ensure correct sizing
