BIGACOVER Jet Ski Cover 120"–135" Universal Fit for 1–3 Seater PWC — 300D Oxford PU Waterproof, UV Protection

BIGACOVER's Jet Ski Cover is a heavy-duty, universal cover sized for 120"–135" jet skis and designed to protect 1–3 seater watercraft from rain, sun, dust, and wind.

This cover was engineered to shelter popular models from Yamaha, Sea-Doo, and Kawasaki while balancing durability with a secure, adjustable fit. Constructed from 300D Oxford fabric with a PU waterproof coating, it combines water resistance, UV protection, venting, and anchoring features to keep your personal watercraft clean and preserved when stored on trailers, docks, or in dry storage.

Will this cover fit my jet ski?

The BIGACOVER fits jet skis with overall lengths between 120" and 135", suitable for most 1–3 seater models. It lists compatibility with many Yamaha, Sea-Doo, and Kawasaki models, but measuring your craft is the best way to confirm fit.

• Fits lengths from 120" to 135" (measured nose to transom).
• Examples: Yamaha VX series and GP1800; Sea-Doo GTI/RXP-X/Apex; Kawasaki Ultra models.
• Includes adjustable elastic hem and three straps for a snug fit on trailers or stands.

How does it protect against water, sun, and wind?

The outer layer uses 300D Oxford fabric with a PU coating that sheds water and resists UV degradation. Design features reduce moisture buildup and help the cover stay put during breezy conditions.

• PU coating provides strong water resistance to keep rain and spray out.
• UV- and heat-resistant fabric helps reduce fading and interior cracking.
• Windproof design plus adjustable cords and straps secure the cover in place.

What features help prevent condensation and wear?

Strategically placed vents allow air to circulate, lowering internal moisture and reducing the risk of mildew and corrosion. The soft, flexible fabric protects finishes while a storage pocket keeps small items handy.

• Left and right rear ventilation holes decrease trapped humidity and pressure build-up.
• Soft 300D Oxford protects gelcoat and hardware from abrasion.
• Integrated storage pocket provides a location for tie-downs or keys while covered.

How easy is it to install and secure on a trailer or dock?

Putting the cover on is straightforward thanks to the elastic hem and three adjustable shoulder straps that clip under the hull or onto trailer rails. A bottom cord lets you tighten the hem for a custom fit.

• Elastic hem stretches for fast initial placement.
• Three adjustable straps with buckles secure under the craft or to trailer points.
• Tightening cord at the base allows fine adjustment for a close fit.

Who this is for: Owners of 1–3 seater jet skis and waverunners who want a cost-effective, durable cover that fits popular Yamaha, Sea-Doo, and Kawasaki models in the 120"–135" length range. It's a practical choice for seasonal storage, winter lay-up, trailer transport, or everyday dock use where protection from weather, sun, and debris is important.
