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.
Review: GTI 130 - This is good quality and fits the GTI 130.

*by J***O on 8 September 2025*

This is good quality and fits the GTI 130.

### ⭐⭐⭐⭐ Jet ski cover
*by D***L on 30 April 2024*

Was looking to replace the current cover due to UV damage. The Trailerable Jet Ski Cover (3 Seats) offers a decent mix of features at a likely affordable price (price information not available in the prompt). The heavy-duty fabric, air vents, and supposedly trailerable design are all positive points.
