When winter's worst comes down upon your head with the strength of a thousand Thors, there's only one thing to do: hunker down in the Marmot Hammer 2-Person 4-Season Tent and be patient. After all, Thors tend to blow themselves out eventually. Everything should pass by pretty quickly when you're holed up in the Hammer, since even the Thors' anger is no match for the 50D Trevira polyester, ripstop nylon, and silicone and PU coatings that shelter you from the elements. Apparently, Marmot made a deal with Loki to mess with Thor, because the single-wall Hammer's also incredibly breathable, so it doesn't turn into an accidental steam room, and superlight, so you don't have to compromise your objectives because your pack's too heavy.
The Hammer has a removable vestibule (with snow flaps, naturally), so you can keep your gear dry or shave extra ounces, and has fully-taped seams to seal out even the sneakiest of moisture. Setup's easy, too, courtesy of an internal guy system and easy two-pole design (the vestibule requires one more small crosspiece), and Marmot even tossed in reflective points so you don't trip over your shelter in the dark. Add in small touches like jingle-free zippers and interior pockets, and you might decide to just stay inside, even after the sky's gone blue.
