    Helium 250

    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.

    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 Fluorocarbon-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.

      Down is the finest insulator that we have. Its warmth to weight ratio, compressibility, long lifespan, and softness are yet to be matched by manmade insulations. For all but the most serious expeditions, duck down is a great choice for both insulated clothing and equipment.
