Weighing in less than most bottles of water, and packing down equally small, the Helium 250 Sleeping Bag is the perfect sleeping bag developed by Mountain Equipment for the dedicated warm weather backpacker.

It’s taken over 50 years of cutting-edge scientific research, lab testing and computer models to get where we are today with our painstakingly optimised Sleeping Bag range. Designs have been improved. Insulation has been refined. And our fabric and construction technology has advanced to entire new levels.

Key to our new collection is the Helium Sleeping Bag range. Our Helium bags are now lighter and warmer than ever before. Efficiently sized, supremely comfortable and low in weight each Helium bag offers outstanding all-round performance for backpackers, trekkers and alpinists.

Super light, highly compressible and densely woven Helium™ 20 outer fabric weighs just 38g/m² yet remains tough and exceptionally down proof. Our 5 baffle anatomically shaped hood and 4 baffle offset foot-box restrict down migration whilst minimising overall weight and bulk.

Minimalist but comfortable bags, built better.
