Big Agnes Copper Spur UL4 Tent -

Popular, well-maintained campsites just don't scratch your itch for wilderness, so you pack up the four-person, three-season Big Agnes Copper Spur UL4 Tent (UL stands for ultralight), and set up camp well away from any roads, bathrooms, or RVs. Although it can't compete with a lighter-than-air one-person tent in the weight department, it weighs barely twice as much as the one-person Copper Spur, and sleeps four without any problem, making it an ideal choice for group or family backpacking trips where weight is still important. The Spur was designed with steep walls and a horizontal crosspiece for extra living space, and a Featherlite DAC hub-style pole system for easy assembly. It also has plenty of creature comforts (for a tent, anyway) like eight mesh pockets, individual media pockets with cord ports, and two large vestibules that comfortably hold packs, boots, and smelly gear, so your happy tent doesn't deteriorate into a pile of stink. 

The Spur also has mesh walls designed to circulate air and let you sleep under the stars when the weather's good, and a ripstop nylon fly with zipper-covering storm flaps and taped seams, ensuring that no water ends up dripping onto your face or soaking your bag. Two doors eliminate the need to stomp over your tent partners' gear and faces, and reflective guylines and webbing take some of the fear out of walking around the campsite in the dark. You can even pitch the Spur using just the poles, fly, and footprint (sold separately) if you're looking for an even lighter setup.
