The Integral Designs brand was started in 1986 and includes five complementary product lines: bivys, tarps, bug shelters, mountain tents, and accessories. All Integral Designs products are designed for multi-day outdoor trips. Product testing is usually done by having the products used in extreme conditions on mountaineering expeditions. The emphasis is on function and long term durability. The designs and features have been developed and refined following extended use in the outdoors.
