These Brit-born nature-sleepers are made from weatherproofed, breathable cotton, are "significantly larger than most two-person tents" (with a separate area for wet stuff/storage), and take but five minutes to set up. Limited-ed designs include a saucily buxom seaside postcard, a giant sandwich, and one called The Nuisance that's scrawled with the phrase "Your Mum's In Here". Though if she's making you a giant sandwich, that's hardly a nuisance.
