The color of this gray sail is perfect, it will match our house nicely.  The fabric isn't really fabric.  It's that plasticy woven stuff.  I'm not sure what it is called.  I think it will hold up well though and boy do we need something strong.  It gets very windy on the plains in Colorado!  The D-rings sewn to the corners seem like good quality and that's pretty important too.  We haven't had a chance to buy poles and install it but will update my review with pictures once we do.  Processing and shipping took a very long time so I hope it ends up being worth it!
