QUALITY SAIL - The material of our shade sail is High Density Polyethylene (HDPE). It is lightweight and resistant to mold and stains. Its weight is 180gr/m2 which gives it tear resistance. Our set includes wall mounting accessories to reinforce the stability of your sail in difficult weather conditions. UV PROTECTION Our sail is designed to protect you from the sun by blocking up to 90% of harmful ultraviolet rays. It will also give you a nice shade space for your garden, yard, patio and more. AIR VEIL - The HDPE fabric is designed to pass air through so the space under the sail is cooler and does not accumulate heat. In the same way, our shade cloths allow a little water to pass through so that it does not accumulate in rainy weather and which could weigh down the sail and tear it due to pressure from too much weight. STRONG SAIL Concave shape and double edge provide stability and sail resistance. The finishes are of quality with durable seams. Each corner has a ring made of stainless steel in the shape of a D to facilitate installation.
