Alpine 800 Long Ultralight Down Sleeping Bag

About the Rab Alpine 800 Long

What is the Rab Alpine 800 Long good for?

The Rab Alpine 800 Sleeping Bag is built for serious mountaineering and cold-weather trekking. Designed for 4-season use, it’s ideal for high-mileage expeditions where reliable warmth, low weight and packability are critical.

How will some of the key features of the Rab Alpine 800 Long enhance my experience?

This bag combines lightweight performance with warmth thanks to a Pertex Quantum outer and 800g of 650FP ethically sourced European duck down. The down is treated with Nikwax Hydrophobic Down, which resists moisture and maintains loft up to 60 times longer than untreated down. It also dries three times faster, all without using harmful PFCs. Trapezoidal box-wall construction eliminates cold spots, and the tapered mummy shape with an angled foot box ensures warmth without sacrificing comfort. A 3D neck collar and drawcord hood lock in heat, while a full-length down baffle behind the ¾ YKK zip prevents draughts. An internal pocket gives convenient storage for essentials.

Why choose the Rab Alpine 800 Long?

If you need reliable insulation in cold conditions without the burden of extra weight, the Rab Alpine 800 is an excellent choice. Made and hand-finished in Derbyshire, UK, it reflects decades of experience and technical refinement. The hydrophobic down, lightweight materials, and thoughtful features make this a go-to for winter adventures where performance, packability and value are key.
