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.

Much needed shade from the California sun.

Material is very durable and well made. Winch kit made the set up and installation super easy. Buying another one for the other half of our pool.

sturdy fabric, look great, create amazing shade....happy with my purchase.

We really like that you can put them how ever you want and they really help to keep us cool
