Bibler I TentOver 25 years of experience and field testing has made the Bibler line of Black Diamond tents among the top in tent innovation and high-quality construction. Pioneering beyond their double-walled counterparts, Bibler's unique single-wall tents are built to withstand some of the harshest conditions on the planet while remaining surprisingly lightweight. You'll find these marvels of design and function on the world’s most intense backcountry expeditions, from Everest to Rainier and beyond. After years of testing, the folks over at Bibler have come up with the ultimate backcountry tent, which has taken its form in the shape of the I-Tent. As with many of the Bibler tents, it's made from ToddTex to make it waterproof, windproof and extremely breathable, while also keeping it light enough (4 pounds 8 ounces) and strong enough to handle wind and snow weight. But what makes it really stand out (or stand up) is that it can be pitched in a super tiny spa

The Bibler I-Tent is super light, super strong, waterproof, breathable and easy to set up. The 2-person I-TENT was originally designed for the extreme mountain climber. This tent can be pitched on ledges that are no larger than your couch! Yet any outdoor adventurer will appreciate the design and features that make it the ideal tent at altitude. The I-TENT weighs an astonishing 4 pounds, 11 ounces, yet rolls up small enough to fit into the side pocket of many internal frame packs. Two poles crisscross inside the single tent wall, eliminating hard-to-thread sleeves, and bending naturally into the eaves of the roof. The result is maximum strength and more headroom per square foot of floor space than any other tent. The single piece bathtub floor has no seams. The door toggles to the side when open. The no-see-um net door is on the interior to prevent the massive ice build-up which occurs on exterior net doors of other brands in winter. Each I-TENT comes with two weatherproof zippered vents at the very peak of the tent to draw out rising moist air. In addition, a hooded vent over the door and a unique covered vent at the bottom of the door provide flow-through ventilation, even in poor weather. Two net pockets hold odds and ends, and it is fully seam taped. Sets up easily in under two minutes.
