This shade sail is made of UV-treated polyethylene that blocks up to 90% of UV rays. That's useful both in terms of limiting damage to your skin and as it relates to managing the temperature on hot summer days. It's also weather-resistant, mildew-resistant, and it comes with all of the necessary hardware to adjust the sail to fit your desired area perfectly and to make sure you get the right tension. You can also select from blue, green, and yellow colors to match your home or outdoor area.
Cost-effective, simple, and flexible shade is something a lot of people are looking for. Many of those people have a backyard, a pool, a tailgate, or an outdoor dining area that would be a lot more useful if it didn't receive so much direct sunlight. If you have any outdoor space that could benefit from sun or UV protection in any way, the 10 Foot Triangle Sun Shade Canopy Sail with Hardware is about as convenient and cost-effective solution as you're likely to find.

The Canopie is exaclty what I wanted.
