SpaCap Hot Tub Covers are made from the absolute best outdoor marine grade fabrics. The typical rigid foam hot tub cover is made from the cheapest material that still appears to have quality. Spa Vinyls are rated by hours of exposure where as Sunbrella Marine Acrylic is rated by years. The largest most expensive yachts in the world use the exact same fabric used on the SpaCap Hot Tub Covers. Sunbrella is quite literally the world standard in outdoor fabric. All vinyl including the top of the line Marine grade is rated by HOURS outdoors and Sunbrella is rated by years.

The underside of the SpaCap Hot Tub Covers are a vinyl-coated fabric similar to that used for Achilles and Zodiac inflatable boats and commercial truck tarps. It has a base polyester fabric that is then coated with vinyl on both sides. It is the same fabric used in commercial fertilizer bin tarps. That means the material can handle some of the most extreme chemical exposure. The thread used to join the SpaCap Hot Tub Covers together, is the same strength and weight thread used to make truck tarps. Every SpaCap Hot Tub Cover is custom made to order in the USA, built to last, and to look good for years to come!

Can a Hot Tub Cover that does not use foam handle a snow load?

SpaCap Hot Tub Covers can handle more heavy snow than any rigid foam filled spa cover because the bottom of the cover is supported by the water in the hot tub. The typical rigid foam filled Spa Covers try to act like a bridge over the spa water. When the snow gets too heavy, the rigid foam Hot Tub Cover will sag or break. As opposed to SpaCap Hot Tub Covers that rest right on the surface of the water, no matter how deep the snow the weight is evenly supported by the water. These air filled Hot Tub Covers have gone through world record snowfalls and to date with thousands sold around the world there has not been even one crushed by a snow load.
