Mountain Equipment Helium 250 Sleeping Bag

Weighing less than most bottles of water and packing down equally small, this is the perfect bag for the dedicated warm-weather backpacker looking to lighten their load.

Using 261g of minimum 700-fill power DOWN CODEX-approved duck down and a high-performance, 100% recycled Helium 20D outer fabric, the Helium 250 is an incredibly efficient but lightweight and packable sleeping bag, perfect for warm-weather backpackers and tourers wanting to decrease their pack size.

Slant-baffle construction through the body maximises warmth, improves packability and prevents down migration, keeping you warm night after night and preventing cold spots. At the foot of the bag, a four-baffle system focuses warmth around your feet, while in the hood, a five-baffle system optimises comfort and keeps the down precisely where it needs to be.

Inside the bag, a 100% recycled Supersoft 20D lining fabric with PFAS-free DWR offers breathability and durability for comfortable nights and a long lifespan, while a full-length Gemini™ entry zip baffle practically eliminates heat loss in this vulnerable area and is stiffened so it won’t catch in the zip. The low-profile magnetic Lode Lock™ closure and collar drawcords are practical and easy to use in the dark.

Designed with a technical yet comfortable Alpine 2.0 fit, Helium bags optimise thermal performance while minimising weight. With a Good Night’s Sleep Temperature of 1°C (34°F), the Helium 250 is the best choice for warm-weather camping and backpacking.
