Of course, that isn't quite the whole story. You'll want a ground cloththe Tarptent folks sell one made of Tyvek for $12 that adds four to eight ounces, depending on the tent (a sewn-in floor is another option, goes for $30, and adds six ounces to the Squall). So that's a slight weight addition, plus if you go with the ground cloth and hit heavy rain, you'll have to do some canal work to get water away from the tent. And the Tarptents' reliance on lots of mesh means that cold breezes will accompany you and your boyfriend's slumber.
But for most camping, in most conditions, why not? The Tarptents are super light, easy to set up, and weatherproof enough for all but severe or very cold conditions. Their top competition, in my view, is Mountain Hardwear's Waypoint 2 ($250; www.mountainhardwear.com), which weighs about three and a half pounds. It has a full floor, and I've found mine to be exceedingly storm-resistant. It's also long enough to accommodate your gangly beau. So you might take a look at one of those, too.
