The SupraRoos Cushion Cover is designed to perform under the toughest of conditions. SupraRoos uses Dupont® two-layer technology that is twice as strong as regular Tyvek® and provides superior protection against high wind and inclement weather. The outer layer provides great UV-resistance while the inner layer adds strength and resistance to sharp edges and corners making the fabric extra tough. If you need to protect your outdoor furniture for long periods of rain, strong winds, or snow, SupraRoos will best meet your needs. Available in white. These outdoor covers are stronger than most vinyl covers, yet light weight. This means the covers are easy to use (no struggling to get them on and off). Also, these patio furniture covers are able to handle temperatures from very low temperatures to very high temperatures.
