GRABADO Jet Ski Cover 420D Waterproof for 121"–135" 3-Seater PWC — UV & Tear Resistant, Windproof Fit

Keep your Yamaha, Sea‑Doo or other three‑seat jet ski safe between outings with a heavy‑duty cover built for long‑term outdoor use. The GRABADO Jet Ski Cover combines a thick 420D oxford shell with a nano‑coating inner layer, reinforced seams and multiple fastening points so your PWC stays dry, shaded and scratch‑free whether it’s stored on a trailer, dock or driveway.

How does this cover resist rain, UV and tearing?

The cover uses extra‑thick 420D oxford fabric with a triple nano coating on the interior to block moisture and prevent abrasion against seats and plastics. Seams are double‑needle stitched and sealed with waterproof tape, and the material is rated for high UV resistance so color and strength last longer.

• 420D oxford fabric with nano triple coating for waterproofing
• Seam sealing and double‑needle stitching to withstand heavy rain
• Enhanced UV and tear resistance for extended outdoor exposure

Will this cover stay secure in windy or stormy conditions?

Yes—the GRABADO cover includes four adjustable elastic windproof buckles and an elastic hem to lock the fabric around the hull. The combination of straps and full elastic hem helps prevent the cover from ballooning or slipping on trailers and docks during gusty weather.

• Four windproof buckles (front, back, left, right) for a snug fit
• Full elastic hem that conforms to the jet ski shape
• Flexible straps simplify installation and keep tension even in wind

How does this cover protect interior surfaces and prevent condensation?

Internal comfort and surface protection are addressed through a smooth nano‑coated inner layer that reduces scratches and two side vents that promote airflow. Venting lowers trapped moisture that can lead to mildew and frost, helping cushions and electronics remain dry between uses.

• Smooth internal coating to avoid abrasion on seats and controls
• Two air vents for circulation to reduce condensation and frost
• Store in the included portable bag to keep the cover clean and compact

What sizes and models does this cover fit?

The cover is designed as a universal fit for most 2‑ and 3‑seater PWCs, specifically accommodating lengths from 121" to 135". It is compatible with common brands including Sea‑Doo, Yamaha, Kawasaki, Honda and Polaris—measure your craft from bow to stern to confirm fit before purchase.

• Fits PWC lengths 121"–135"; ideal for many 3‑seaters
• Compatible with Sea‑Doo, Yamaha, Kawasaki, Honda, Polaris and more
• Advice: measure hull length and key accessories prior to buying
