    A bit about us

    Purveyors of the very finest climbing equipment for 50 years.

    Joe Brown is considered the foremost rock climber and mountaineer of his generation, and perhaps the greatest all round mountaineer ever. You can read a biography of his climbing career if you click here.

    In 1966 Joe opened the Llanberis climbing shop with his wife Val. The Capel Curig shop opened a couple of years later and over the years the shops have earned the reputation of being among the best specialist climbing equipment and outdoor gear shops in the UK.

    As an independent mountaineering, climbing equipment and outdoor business we focus on providing honest and personal advice, as well as great ranges of mountaineering, rock climbing, ice climbing, walking, hiking, expedition and alpine climbing equipment.

    So if you find yourselves visiting Snowdonia, which we hope you will, please pop in and see us at one of our locations in Llanberis or Capel Curig. You will be sure to find an Alladin's cave of technical gear and equipment from all the major quality specialist outdoor brands. Or if at home or work then enjoy browsing or shopping on our web site.

    Most of all though enjoy your time outdoors whatever your pastime, have fun and be safe!

    You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!


    With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

    So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

    Mountain Equipment Xero 550 Sleeping Bag - Regular Description

  • Brand : Mountain Equipment
  • Season : AW16
  • Code : 5064219
  • Weight : 0KG
  • The Mountain Equipment Xero 550 is a very popular bag for backpackers thanks to its good weight and packed size, coupled with a good temperature rating. There is an EXL elasticated lining, which provides a closer fit than most bags without restricting movement – and this system makes the bag feel a little warmer than others. Mountain Equipment's newly developed Alpine Fit combines ground level seams and re-profiled down distribution to optimise thermal efficiency and minimise weight and bulk.The end of the bag is profiled to prevent the feet from compressing the insulation, and the side zip gets a nice wide anti-snag strip and a draught baffle, while the shoulder baffle is particularly wide and well-filled to help trap warm air inside the bag. Wth a comfort temperature of -1°C, the Xero 550 is ideal for the fastest moving Alpinists, runners and trekkers where weight and pack size are everything.

    Mountain Equipment take great pride in sourcing the best ethically produced down for all their sleeping bags. With this comes the DOWN CODEX scheme, a scheme that has been developed to manage and reduce risk in the down supply chains, to ensure that both animal welfare and quality were put at the heart of each and every one of Mountain Equipment's down products. You can find your 12 Digit code printed on the DOWN CODEX® stamped label inside of your product, this enables you to simply enter this code via the DOWN CODEX website to access to specific information relating to the down in your product.
