This shade sail is made of a thick but flexible material that should provide just the right amount of protection from the sun without being a total "sunblock" (or completely waterproof) and the reinforced attachment points on the sail seem sufficiently strong. I haven't yet installed it, but the included kit appears to be very comparable to the separate installation kit I ordered just in case the included kit was flimsier or more difficult to use. This particular brand of sail offered a lot of different size options, which is ideal if you are looking for a sail to fit a space with unequal distances between the triangle points. The sail I ordered measures 20' x 20' x 28.3'. it came with a installation hardware kit but I can't yet comment on whether the hardware kit works well. I also ordered another hardware kit in case I needed a different installation option than the one included. Unfortunately, Wayfair said it delivered both when I never received the additional hardware kit. After waiting 3 days to see if there was a problem with how the item was scanned, I have reported the missing delivery and hope that I will receive that other installation kit so that I can choose which kit will work better for installing the sai.
