Whether you own a Legend III or a Sunshell, the materials underneath matter just as much as the fit. Every cover is built with 30oz marine-grade vinyl, double-stitched seams, and YKK-style zippers, reinforced with heavy-duty handles and color-matched safety straps rated for daily sun, wind, and water exposure. That construction keeps the seal airtight for years, instead of sagging or cracking the way thinner, single-stitched covers often do after just a season of regular use.

A cover that's heavy, waterlogged, or splitting along the seams is already letting heat escape, whether it shows up on your energy bill yet or not. Swapping in a new Hydro Spas cover, whether for a Comet II, Platinum I, Sandstar, or any other model, is straightforward: confirm which one you own, and we handle production from there. Every order ships free and comes backed by an industry-leading warranty.
