26 ounces including stakes, which are included. Double wall, fully enclosed, very stable, requires only four stakes to set up, and does use trekking poles or you can get poles for it too. Great usable vestibule space and one of the most innovative one-man tent designs for sure. Can be used as a net tent only or a tarp only. Look at the setup video for this one and you'll see what a great option it is.
