The Desert Camo pool cover is a extra heavy-duty solid winter cover made with Fusion-Extreme technology. Solid pool covers do not allow water to pass through their material. This is the only cover with Fusion-Extreme Technology. This unique Fusion-Extreme technology allows us to produce this amazing military-style camo pattern. This cover includes a 4 ft. overlap, making this cover easier to secure to your pool than other pool covers. Please order by pool size, as the overlap goes beyond the pool size listed. If you have a very large top rail, please consider a larger pool size. The cover should be able to comfortably float on the pool water without excessive stress. The camouflage top of this cover is coated to prevent UV damage. The Desert Camo Winter Cover features a military-grade 10 ft. x 10 ft. scrim (threads per sq. in.). This cover is constructed a military-grade polyethylene material that weighs 3.3 oz. /yard2. 2-premium grommets are placed on center every 4 ft. With these grommets, you should use the included winch and all-weather cable to secure your pool cover. The Desert Camo Winter Cover includes a 12-year warranty.
