This tent is very similar to Sierra Designs' Clip Flashlight 2, except for the pole design. They are essentially the same weight, plus or minus an ounce.
The Vapor Light 2 appears to have more usable headroom and is free standing, but in my opinion, the Clip Flashlight 2 is more bombproof to high winds. It is my belief that the Clip Flashlight 2 should be able to withstand quite high winds from the foot end if you add additional guys under the fly. I wouldn't suggest using the Clip Flashlight 2 for more than one person, except in an emergency, and I might feel the same way about this tent, despite it having a broader peak. For two people, I would be inclined to carry a few more ounces and go for something with more room and two doors like an REI Quarterdome.
