Weather Smart® is a man-made industrial yarn that has undergone improvements in the aesthetics, softness and further anti-microbial enhancements to prevent degradation from outdoor exposure. Weather Smart® is a lot softer that than any synthetic yarns used in other rugs. With a 0.01 percent moisture regain, this yarn does not absorb water, dries very quickly and resist stains due to its nonabsorbent properties. Cleaning is as simple as washing briskly with mild soapy water; bleach can also be used in the cleaning of this yarn as it does not affect the yarn's color. Weather Smart® is also produced with built in UV blockers which provide colorfastness and true colors for years of enjoyment. The softest and best choice.
