SRIMMIT Jetski Cover 3-Seater 136–145 in Black — Heavy-Duty Waterproof UV-Resistant Protection

SRIMMIT Heavy Duty Jetski Cover for 3-seater PWCs is a waterproof, UV-resistant protective cover sized for 136–145 inch jet skis, built to block rain, sun, dust and trailering wear.

This durable cover is engineered for owners who store or tow a three-seat personal watercraft and want long-lasting protection without fuss. Constructed from thick 420D Oxford fabric with a six-layer nano-coating, it balances weather resistance, breathability and a snug fit. Reinforced stitches and windproof buckles keep the cover secure while vents cut down on moisture build-up so your craft stays dry and finish-safe during off-season storage or short trips.

How does this cover protect my 3-seater jet ski from rain and sun?

The SRIMMIT cover uses 420D nano-coated fabric rated for 12,000mm waterproof resistance and provides SPF 85+ UV protection. The multi-layer coating sheds heavy rain while blocking harmful sun rays that fade plastics and upholstery.

• 12000mm water pressure resistance prevents seepage in heavy rain
• SPF 85+ UV barrier reduces color fading and material degradation
• Reinforced seams with waterproof tape stop edge leakage
• Nano-coating preserves a smooth surface that won’t scratch your finish

Will the cover stay on during trailering or windy weather?

Yes — the design includes four adjustable elastic windproof buckles and a full elastic hem to hold the cover tight against wind and motion. It’s intended for low-speed trailering and storage; for highway towing above 70 mph the manufacturer advises caution to avoid damage.

• Four windproof buckles anchor front, middle and rear securely
• Elastic hem prevents wind lift and reduces flapping noise
• Flexible straps attach to buckles for extra fastening while towing
• Marked "FRONT" simplifies correct installation every time

How does the cover handle moisture and condensation?

Dual air vents on each side keep internal air moving to lower condensation and frost risk. The vents reduce trapped humidity that can otherwise promote mildew or moisture staining while the tight hem minimizes water pooling on the cover.

• Two vents per side encourage passive airflow and evaporation
• Tight elastic hem minimizes surface water accumulation
• Tip: tilt the rear or use a support pole for unusual hull shapes to avoid pooling
• Not fully sealed—venting helps preserve finishes during long storage

Will this cover fit my jet ski model and how do I care for it?

The cover fits most 3-seat jet skis 136–145 inches long, including Sea-Doo, Yamaha Waverunner, Kawasaki, Honda and Polaris models with standard-height handlebars. It’s easy to rinse clean, but the nano coating means hand washing only to maintain water resistance.

• Designed for 136–145 in 3-seater PWCs; measure accessories and raised handlebars
• Hand wash recommended; rinse with hose or wipe with damp cloth
• Comes with a compact storage bag for tidy transport and seasonal storage
• Not fireproof — avoid open flames and wait for engine cool-down before covering

Who this is for: the SRIMMIT Heavy Duty Jetski Cover is ideal for PWC owners who need a robust, weatherproof shield for outdoor storage and low-speed trailering of 3-seater models. Choose this cover if you want high waterproof ratings, UV protection, secure windproof fastenings and breathable vents—just measure your craft and any aftermarket accessories first to ensure the right fit.
