Right from the unboxing, you can tell that this sail shade is very lightweight. We got the 16’ x 12’ rectangular one in tan. The corners and stitching appear to be well constructed and able to hold up over time and stress. The material itself is fairly dense for a sail shade, but very lightweight. The included stainless steel hardware is solid and very adjustable, so as to be able to tighten or loosen the shade with simple torquing. I am curious how much passive rainweather protection this will additionally offer, as the weave of the material is quite tight. Would recommend
