## Description

desertcart.com: Jetski Sea-doo Cover Waterproof, Upgraded 420D Heavy Duty Jet Ski Covers,2 Air Vent Marine Grade UV Resistant for Seadoo Waverunner Polaris from 136" to 145"(Black)

Review: Stays on even without the added straps - I really like this Sea-Doo cover and it fits my three seater well. The elastic is easy to fold over the back corners. It has straps or I can strap it onto the lift to keep the cover down. I really like the color will reflect sunlight off the top with the silver stripe. It’s thick enough that it has not torn in the wind or storms, but it’s light enough and easy enough to take off by myself and fold up into a small form.
Review: good fit! accurate sizing - just put it on for the first time but it fits kawasaki stx 160lx and seems of good quality! has a good strap system to keep it tucked around the ski. havent towed it yet but it does have air vents not sure if that helps. will update if things change.
