Best Rab Sleeping Bags (UK) of 2022

Last update by Jasper

Rab merchandise has been around for a very long time, with advanced designs and technology for extreme temperatures. The company was the first manufacturer to use Pertex in his sleeping bags and down jackets.

The ideas were conceptualized by Rab Carrington back in the 1970s because of his own love of hiking and surviving in very cold temperatures. His innovative approach to his line of gear takes the wilderness and tames it, all with style and protection. He truly understood the requirements of climbers and hikers. Rab sleeping bags are highly durable and lightweight and ideal for putting in a pack due to being down filled by hand in their factory in Derbyshire, UK. This allows the company to ensure that by the time the bags reach customers, they have never been compressed or stored in a way which could be harmful for the down inside – you are guaranteed comfort and warmth during chilly and biting temperatures as well. Rab’s down products are traceable under the European Down and Feather Association Codex, which means that the down is ethically sourced ensuring that it is a by-product of a slaughterhouse or harvested during molting periods and is not illegally live-plucked.

Rab Men's Andes 800 Check latest prize

The Rab Andes sleeping bags are similar to the Expedition range, in terms of the warmth they provide, but their shape is more performance orientated. This increases warmth-to-weight and reduces pack size. The Rab Andes 800 is a mummy shaped version that is slightly warmer than some other bags, but quite lightweight at the same time. This performance is achieved by using the most efficient down, so you get 800+ fill power down, made up of 90 per cent down and just 10 per cent feather. This down is then treated to make it water-resistant, so it absorbs less water, retains more heat when damp and dries faster.


  • Pertex Endurance nylon is used on the outside of the bag to also enhance water resistance while maintaining breathability.
  • Compression stuffsack available to pack up the Rab Andes sleeping bags when you leave.
  • Full-length zip with a very wide insulated baffle plus a huge shoulder baffle for better comfort in the cold.
  • The bag can be used up to 8000m altitude or on exposed belays, in temperatures as low as -22°C.
  • Longitudinal foot and chest baffles to minimise down migration and incorporated with internal Flowgate technology respectively.
