NO-SLIP skid resistant coating and textured woven surface features contribute to a safer walking surface. - Longer UV resistance
FelTex can be left uncovered and exposed to the elements for 6 months. - Will not warp, wrinkle or crack
Superior lay-flat properties and no water absorption keeps FelTex from warping, wrinkling and cracking in cold weather. - 30 year limited warranty
