Designed for high altitude mountaineering and the harshest conditions the Andes bags balance warmth, weight and top of the range features for excellent performance when it is needed most.

Rab says:

The Andes 1000 offers similar warmth to the Expedition range, in a more performance orientated shape, maximising warmth-to-weight and reducing pack size.

With 1000g of high quality 800FP ethically sourced European Goose Down, the Andes 1000 is designed for use up to 8000m altitude or on exposed belays, in temperatures as low as -27°C. Styled in a 'mummy shape' to reduce pack size, the Andes 1000 uses a combination of high quality Pertex® inner and outer fabrics to provide increased durability and windproof. Key features include longitudinal foot baffles to minimise down migration, chest baffles with internal Flowgate® technology and anti-snag webbing tape throughout.

The Andes range of sleeping bags are hand-filled in Derbyshire, UK.

Rab's Andes 1000 Down Sleeping Bag is a bag designed to cope with the harshest conditions. With 1000g of 800FP Hydrophobic Down and a temperature rating of -27°C this is a serious piece of kit. The bag uses a combination of vertical and horizontal baffles with a trapezoidal box chamber design to maximise warmth and loft whilst minimising down movement. The quality Pertex Quantum fabrics used aids performance but also feels nice to the touch and adds durability. The bag lofts quickly and provides instant warmth.

Additional features such as the neck baffles, angled footbox and internal drawcords adds to the comfort level. The bag is generously sized and there is certainly a lot of space if you are just wearing base- or thin layers inside, which is obviously something to consider in terms of keeping warm during the night. The drybag provided is a welcome addition and with taped seams, a roll top closure and heavy weight fabric is does a great job of protecting your bag. There is a small zip pocket just above the neck baffle but it's too small to be of much use.

What is the 'RAB Sleep Limit'? - The recognised method of testing sleeping bags is by using the standard EN13537 temperature ratings, which are carried out by independent testing houses. The test is performed with the sleeping bag resting on an insulating mat to simulate the bag in use. The same sleeping mat is used for all testing of all sleeping bags.

RAB's view is that the sleeping mat used is inappropriate for bags designed for very low temperatures because a user would be sleeping on a highly insulative winter orientated sleeping mat, not the standard one used in the test. The test results would therefore indicate a lower performance for the sleeping bag than a user would experience in a typical situation.

RAB have therefore defined their own 'RAB Sleep Limit' as the equivalent 'Comfort limit' but based on their athletes experience and extrapolating results from other bags.
