Review: Great Value - Delighted , bought this when Prime sale was on , didn’t need it yet but for 9.99 thought I’ll buy it. Can’t tell you if it 100% waterproof yet, but it looks it, I’ve unpacked and tried it on ski and all good Review: Measure your ski and buy the cover that is closest fit - Pleasantly suprised by this cover, first off when it comes it comes vacuum packed in a bag in side a storage bag, it smells when you puncture the outer bag, it smells of plastic I suppose so don`t open it indoors it smells rank, initially. However that aside I took the cover out of the storage bag and unfurled it as it was compressed together, the material is more plasticy than canvas but has an inner silver lining and mine was black exterior despite being a bit plasticy the material is strong and looks pretty water proof. The cover has a label inside for care instructions and one that says FRONT. Took it to my 1999 Seadoo GSX RFI to try it out slotted it over the front, up over the handle bars and seat and hooked over the stern. Then got out the 4 securing straps. These fitted easily and were plenty long enough. The elastic hem of the cover closed arount the hull and I pulled up on the adjustable securing straps the fitting was easy, the ski is properly covered and the cover is not saggy or too loose looking. Today is quite breezy but I don`t think even the strongest wind is going to blow this bad boy off. Took a few photos of the fitted cover to show the good fit. Overall for the price this is GOOD QUALITY, WELL FITTING EASY TO USE COVER I am pleased with it. Will trim the access off the securing straps then all will be good. I would say that the images on the listing do make the cover material look more luxurious than it actually is but that being said the material is light but strong and hopefully it will squish back down into its stowage bage when the time comes. I am happy with the quality and fit for the price. ## Features - Heavy Duty Jetski Cover Waterproof Outdoor: Jetski Covers is made of thick 420D oxford fabric with 6 layers of Nano material coating inside, so the inner layer is extra smooth,soft and resilient.It won't scratch your motorboat.Anti-UV: Ultraviolet-proof(SPF) up to 85+.Double-needle sewing process at the joints, adding waterproof strips, able to resist 12000 MM water pressure.It is better in tear resistance and UV resistance. - Protection For Your Jet Ski: 4 adjustable and elastic fixed windproof buckles (located at the front, middle and rear), the sea doo jet ski cover can be tightly fixed on your boat vehicle even in stormy weather, making your sea doo safe, reliable and dry.The sea doo cover that truly resist the wind, rain, sun and snow.Protect your trailerable motorboat outdoor storage from rain, UV radiation, dust, scratches, rips, bird droppings, fallen leaves and etc. - Four Upgrade Details: Air Vents On Both Sides:Keep the air circulation in the jet ski covers and the seat dry, prevent frost.

Material feels like it should be waterproof but time will tell. I Purchased the XL 115-120 inch version and it fits my Seadoo RX well but would have been nice to get the size down but it was not available. ## Frequently Bought Together - Jet Ski Cover Waterproof,Upgraded Heavy Duty 420D Jet ski Covers with 2 Air Vent Marine Grade UV Resistant for Seadoo,Yamaha,Kawasaki,Waverunner Polaris from 121" to 135"(Black) - Botepon Bungee Dock Lines - Quick and Easy Dock Rope for Jet Ski, PWC, Seadoo, WaveRunner, Pontoon, Bass Boat - WavesRx Soft Loops Jet Ski Cleats | Secure Loop Straps for Attaching Docking Bumpers, Fenders, Anchoring Line, Bungee & Dock Rope to your Jetski | Must-Have PWC Accessory for Your Waverunner or Seadoo --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/631692736-jet-ski-cover-waterproof-upgraded-heavy-duty-420d-motorboat-cover](https://www.desertcart.tn/products/631692736-jet-ski-cover-waterproof-upgraded-heavy-duty-420d-motorboat-cover) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-29*
