This sail shade is exactly what we were looking for.  Our patio is only partially covered so, during the summer, it is miserable to sit outside. We are having a large party today and the small tents we have will not accommodate our guests in keeping them sheltered. The sail is perfect for breaching the divide between patio roof and tents!! The material is a decent quality.  Because we will be using this on a temporary basis, I wont be able to speak to how it will handle wind or weather.
