RAB

This tapered, 650FP duck down bag is built for mountain adventures. Ideal for cold, winter conditions, it's designed for alpinism, mountaineering, trekking, bike or backpacking. It has a wind resistant Pertex® Quantum outer and offers excellent value.

Rab's Alpine range is built for the mountains, whether you’re high in the Alps or deep in the Himalaya, on foot or two wheels. Offering a good warmth to weight ratio and a low bulk design, the Alpine 800 is perfect for winter mountain adventures at altitude. It is filled with 800g of 650FP duck down and covered with a wind resistant Pertex® Quantum outer with a recycled nylon lining.

Engineered to maximise down performance, the Alpine bag has clever construction. Trapezoid boxwall baffles allows the down to fully loft, eliminating cold spots, and maximising warmth. The chevron baffle design improves down stability, distributing the down evenly around the whole body. In addition, the openings on the Alpine bag have been designed to reduce heat loss, with a 3D-shaped, down collar that can be cinched in snugly to trap the heat, and a down-filled baffle along the zip to prevent heat from escaping. Complete with a narrow mummy fit and angled footbox, the Alpine is designed to cut down unnecessary bulk and weight, whilst ensuring a comfortable night’s sleep.

Hand-filled in the UK, all Rab's down bags benefit from never having had their down compressed before use, maintaining the down’s loft and warmth.

Unique baffle filling for a better night's sleep

Hand Filled In Derbyshire. Rab hand fill all their down sleeping bags at their factory in Derbyshire, UK. This ensures that every baffle is filled as required and that the down within has never been compressed or stored in a way that could impair performance. The bags are filled using a smaller diameter pipe and a compressed air system, which blows the feathers into each chamber. Before the bags are filled, one empty shell from each batch is weighed to ensure they are within tolerance. Precision scales are then used to measure the down for each chamber and, once complete, the finished bag is weighed again. To avoid being rejected, the bag’s total weight must be less than 10% over and cannot go under the intended weight. Scales are accurate to 0.5g and are routinely re-calibrated using weights of 1000g, 100g, 10g and 1g.

Warm and protective, the Ascent Pro 800 is ideal for winter conditions. It has a generous wide fit, ensuring a comfortable night’s sleep for the weary mountain explorer. Filled with 800g of 650FP duck down, it is a very warm sleeping bag, with space to wear extra, bulkier layers inside if using in seriously cold temperatures.

With Pertex® Quantum Pro wind and water-resistant outer and hydrophobic duck down, it copes well with wind, condensation, and damp conditions, ideal for snow-holing or an exposed bivi ledge. Warm enough to deal with plummeting temperatures it’s a great all-round adventure, winter sleeping bag. Built with trapezoid-shaped, box wall baffles that stack neatly together, the down inside is encouraged to fully loft, maximizing insulation and reducing the appearance of cold spots.

Rab has taken everything they know about lower impact design and applied it to what they do best. These resilient synthetic bags are filled with 100% recycled Stratus™ insulation, and lined and covered with a tough, 20D, recycled Atmos™ fabric with ripstop.

The ¾ length zip has an additional baffle along its length that acts as an effective draught excluder with an anti-snag zip guard.
