Mountain Equipment Gasherbrum Down Jacket

This is our number choice for Polar Expeditions and high altitude Mountaineering. An exceptionally warm ultra-light expedition down jacket, proven on the longest Polar journeys and the coldest routes at altitude.

Mountain Equipment began in 1961 due to a need for specialist down gear. Over 60 years later, the Gasherbrum Jacket continues that tradition, bringing together all our expertise and experience with modern materials and technology.

The Gasherbrum provides crucial insulation for those going to the world’s highest and coldest places in lightweight style where every gram counts. Proven on the longest human-powered Polar Journey in history, it was used for over 100 days on a return trip to the South Pole, and it’s seen use up to 7000 and 8000 meters by experienced users taking alpine style climbing to the highest mountains.

360g of our highest quality Goose Down is controlled with a full box wall construction for maximum warmth, each baffle being optimised in shape and size to maximise the performance and loft of the fill. Our elasticated EXL system in the back of the jacket helps this further. The EXL system adds no weight to the jacket, but gently hugs the user to dramatically reduce dead space between layers and greatly reduce compression of the down. EXL continues into the ultra-protective hood, where it not only increases warmth but also helps to accommodate a helmet or other layers with the minimum of adjustment in conditions well below zero.

A Drilite Ⓡ Loft outer shell provides complete protection from the wind, and a very high level of weather resistance alongside the breathability required to prevent moisture buildup during extended use. Internal mesh pockets are a crucial feature to prevent water bottles from freezing and ensure that spare gloves and mitts stay warm.
