Mountain Equipment Annapurna Men's Jacket - Clearance

Since its release in 1970, Mountain Equipment's Annapurna remains a popular choice for extended use in sub-zero conditions and polar travel. Fifty years later, it continues to be a go-to for extreme cold, combining the best insulation technology with design insights from countless high-altitude and polar expeditions. Built for peaks up to 7000 metres and extended sub-zero conditions.

The jacket's 700-fill duck-down insulation is held in box-wall chambers that trap air and retain body heat. A double-layer baffle construction in the arms boosts warmth, wind resistance, and mobility, reducing cold spots and down migration in key areas like the elbows. Polarloft synthetic insulation panels across the chest, shoulders, and lower sleeves offer extra wind protection and resist compression from heavy packs. The DRILITE Loft outer is windproof and water-resistant, protecting against snow and harsh winds.

Expedition features include a pleated halo baffle around the hood, which adjusts to fit snugly around the face, and a neck ruffle that traps warm air, keeping the head and neck insulated. The modern, streamlined fit allows full movement, while durable moulded zips work well in harsh weather and with gloves.

Technology

Fair Wear Foundation Mountain Equipment is a member of the Fair Wear Foundation, an independent, non-profit organisation that works with brands and factories to improve working conditions for garment workers.

Drilite Loft Drilite Loft is an exclusive range of highly water-repellent fabrics used in Mountain Equipment's insulated clothing and equipment. A highly breathable, lightweight, and very water-repellent fabric, those three hallmarks continue with modern Drilite Loft fabrics.

Down Codex Down is the finest insulator that Mountain Equipment uses. Its warmth-to-weight ratio, compressibility, long lifespan, and softness are yet to be matched by manmade insulations. Down is responsibly sourced in line with DOWN CODEX and RDS standards, ensuring high levels of animal welfare.

Offset Construction Offset construction products have a unique structure that imparts greater wind resistance, greater warmth, and fewer cold spots than traditionally constructed down products. It is also softer and more comfortable to wear than a full box-wall jacket.
