The TarpTent Moment is a solid tent. I've waited out North Carolina thunderstorms in it as well as some good High Sierra snowy nights. Roomy, with a big vestibule. Not the greatest as far as condensation is concerned, but adequate venting and mine has never leaked. A little heavy, but the optional pole makes it freestanding, and sets up faster than you can say "TarpTent."
The geometry of the tent makes it roomy for one, but you'd have to spoon with your tentmate. Lots of room around the middle for gear or tossing and turning, but not much at the head or foot ends.
