    Helium 250 Women's

    Using 242g 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.

    Using 242g 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 to 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 exactly where it needs to be.

    Inside the bag, a 100% recycled Supersoft 20D lining fabric with PFC free DWR offers breathability and durability for comfortable nights and a long lifespan, while a full-length Gemini™ entry zip baffle practically elimates 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 effective and easy to use in the dark.

    Designed with a technical yet comfortable women’s-specific Alpine 2.0 fit, Helium bags optimise thermal performance while minimising weight. With a Good Night’s Sleep Temperature of 3°C (37°F), the Helium 250 is the best choice for warm-weather camping and backpacking.
