Mountain Equipment initially made a name for themselves using down insulation, and Peter Hutchinson and Pete Crew made the first high performance sleeping bags in the UK as early as 1961. The company is now a stalwart of the British outdoor clothing and equipment industry, and are best known for their exceptional range of down sleeping bags. The Helium 400 being one of the most popular. Though their clothing is also of the highest quality; their goretex hard shells are some of the best in the business, and hold their own against competitors with much higher price tags. They are very much a part of the outdoor zeitgeist, and some of the best British mountaineers and rock climbers from every decade from the sixties to the present day have been associated with the development of Mountain Equipment clothing and equipment.
