I bought this for two reasons - light weight and rectangular shape. It is 4lbs, just as advertised and for the square feet that is incredible. The material is light, but it feels tough. The rectangular shape allows you to sleep either way depending on your site. A bonus was the color-You can stealth camp with ease. The flaw is that the spreader pole applies lift to the edges of the fly and pulls it up above the screen. It takes some serious stake hold to pull them down. I can see this being a problem when we camp on the granite in Ontario next summer. I camp with my young sons so this is a much appreciated improvement, since I have to carry all the weight.
