With a design that eliminates wasted corner spacehence wasted weightthe Evolution has two doors, two vestibules, a legit two-person floor, and a comfy 42 inches of headroom.

Impressively, this featherweight didn't bend during an early-winter storm that dropped several inches of snow. Just use TLC when pitching the ultralight fabrics on a granite slab. 3.4 lbs; www.bigskyinternational.comBonus: Save another five ounces with carbon-fiber poles ($85 extra).Bummer: If left open, the vestibule door lets rain leak into the inner tent.
