Mountain Equipment K7 Men's Jacket

A highly insulated down jacket designed for winter climbing and mountaineering at altitudes above 5000m.

Initially created as a last line of defence for demanding Alpine-style climbs at high altitude, the K7 has been tested on some of the most challenging expeditions, from the Slovak Direct on Denali to a Piolet d’Or-winning first ascent of Nyainqentanglha’s South East Face in Tibet. It has since evolved into a widely favoured down jacket, suitable for environments ranging from the 6000m trekking peaks of Nepal to Aconcagua and the Polar regions. The qualities that make it indispensable for elite mountaineers are equally valuable for those embarking on their first remote expedition.

The K7 Men’s Jacket incorporates 300g of premium Goose Down, providing optimal insulation through a full box-wall construction that eliminates cold spots. Every baffle is carefully filled and sized to achieve maximum performance and ensure full loft. The jacket's elasticated EXL system at the back further enhances insulation by gently hugging the wearer, reducing dead space between layers and preventing compression of the down without adding extra weight. This EXL system continues into the ultra-protective hood, boosting warmth and ensuring compatibility with a helmet or other layers with minimal adjustment, even in sub-zero conditions.

The Drilite Ⓡ Loft outer shell is completely windproof and highly resistant to weather, while remaining breathable enough to prevent moisture buildup during extended use.
