Silver Shade can reduce enclosed area temperatures by up to 20%! Eliminate the heat build-up problems of conventional shade tarps and tents that absorb the suns rays, generate heat and trap it inside. This highly reflective fabric acts like a mirror, reflecting away the sun and its heat, while facilitating any cooling air flow. The fabric is durable, light weight, easy to use, rot and mold resistant; it wont run or unravel and can be washed with a garden hose. These shades are unbeaten in shade and cooling because they are made of the highest-grade mesh reflective fabric available (70% shade).
