Stay warm thru spring, summer and autumn

There are some trips where you just can’t afford for your kit to weigh you down. But you don’t want to be shaving grams at the cost of performance. That’s why we love Western Mountaineering bags – their premium materials and meticulous designs result in sleeping bags that are impossibly light yet incredibly warm. The Ultralite is a full three-season champ that weighs just 880 g – and that’s for the biggest size, which will accommodate adults up to 200 cm tall. But it has an impressive comfort limit of -7 degrees celsius. It comes with all the features you’d want from a top end bag including full baffles, a full-length zip and draught protection. Quite simply, this is the perfect bag for adventures in variable conditions throughout prime camping season and beyond.

    • 850+ FP European goose down fill
    • Sleeping bag shell materials are treated with a fluorocarbon free Durable Water Resistant finish (DWR)
    • These fabrics are constructed from yarns that are 12 denier or finer with up to 420 threads per square inch
    • How to use: Your bag should always be placed on a waterproof ground cloth to keep dirt and other forest litter from soiling the outside shell.
    • Cleaning your bag: The best way is to hand wash it in a bath tub or you can use a front loading washing machine. Only use a soap especially prepared for down products. When you hand wash, fill the tub with warm water, add down soap and put the bag in the tub. A tip here is to keep your bag in its stuff sack and put the whole thing underwater.
    • Things to avoid: Dry cleaning is not recommended since the solvents can strip away natural oils contained in the down. Never use a top loading or agitator machine as this can damage the baffle construction. Do not leave your sleeping bag stuffed in its stuff sack or in a plastic bag for long periods of time. Air dry your bag in the sun or in a tumble dryer before storing it.
  • Ethically Sourced Materials - Uses responsibly sourced European goose down, sourced from free-range breeding geese, not birds produced for the meat trade, and never live plucked or force-fed.
  • With an offering of over 30 different models, Western Mountaineering can provide you a sleeping bag for any event, outing, or expedition requiring the lightest and warmest bags.

    A dedicated search for the finest raw materials, meticulous design and unsurpassed workmanship have come together to provide you the highest quality sleeping bags available anywhere.
