Alpine 400 Ultralight Down Sleeping Bag

About the Rab Alpine 400

With over 30-years of experience, Rab sleeping bags are built on tried and tested designs; crafted using the highest quality fabrics with an attention to detail that makes them a trusted name in outdoor equipment. Each Rab sleeping bag is designed, hand-filled, stitched and finished in Derbyshire UK.

Forming part of the Rab Alpine Series, the Alpine 400 sleeping bag delivers a compact and lightweight design with a host of technical features for long-distance trekkers and alpinists looking to keep their gear carry to a minimum.

A lightweight and highly durable Pertex® Quantum shell fabric keeps the pack weight low while 400g of 650FP ethically sourced European duck down delivers highly compressible insulation for a travel-friendly pack size. Nikwax Hydrophobic Down treatment continues to insulate even when damp while maintaining loft 60 times longer than untreated down and drying 3 x faster - all without the use of PFCs. Down fill is held in trapezoidal box-wall chambers to maximise loft and warmth while eliminating cold spots.

The Alpine Series cuts out excess bulk thanks to a tapered mummy fit with an angled footbox to keep your feet warm but still allow for comfort and movement. A 3D down-filled neck collar and drawcord hood provide a snug fit to seal in the warmth while a 3-quarter length YKK main zip provides ease of access backed by a full-length down baffle to exclude draughts. An internal pocket lets you keep a torch or other smaller items close to hand.

When it comes to exploring the outdoors, the Rab Alpine 400 gives you a high-performance sleeping bag well suited to high-mileage treks and mountaineering trips. With a low pack weight and a pocket-friendly price-tag, this bag has been optimised for the fast-moving alpinist and hiker wanting a compact sleeping bag with a balance of low weight, warmth, and affordability.
