Caves, tepees, wall tents, those green canvas triangles that caused hypothermia in so many Boy Scouts鈥攊n one form or another, ideas borrowed from these flawed shelters appear in their modern descendents. But designs didn鈥檛 move forward until the late 1970s, when freethinking engineers at the North Face started toying with futuristic concepts. Here鈥檚 a look back at a few significant breakthroughs.聽
The North Face Oval Intention
Buckminster Fuller鈥檚 geodesic domes inspired the 1975 , but its construction was made possible by Easton Aluminum, a baseball-bat manufacturer that produced the tent鈥檚 revolutionary flexible poles. For the next 20 years, dome designs reigned supreme.聽
Sierra Designs Clip Flashlight
In 2001, the Korean company DAC came up with plastic sockets that could be welded onto a tent鈥檚 exterior. This allowed poles to be attached to the tent rather than held in place by sleeves and grommets. Designers used the innovation to vary the lengths of poles and make new architectural choices that saved weight. An iconic example: Sierra Designs鈥 nonfreestanding Clip Flashlight, weighing just under four pounds.聽
Big Agnes Fly Creek
After years of experimenting with increasingly light but tough materials, Big -Agnes stunned tentmakers in 2009 with the two-pound, weatherproof鈥攁nd mostly minimalist鈥擣ly Creek backpacking tent. It remains a paragon of fast-and-light design.
Marmot Force聽
This three-person, three-season tent arrived in 2015 and was a welcome backlash to decades of spartan minimalism. Though the full-featured abode still weighs in at under four pounds, it makes numerous concessions to comfort, including side pockets for phones and a fully functioning vestibule to keep, say, a generator dry.
