Helium 400 Women's
Using 403g of minimum 700-fill power DOWN CODEX-approved duck down and a high-performance, 100% recycled Helium 20D outer fabric, the Helium 400 is warm, lightweight and ultra-compressible for easy packing. Efficiently sized, supremely comfortable and very low in weight for backpacking and cycle touring while still being warm enough to cope with chilly nights.
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 essential 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 -5°C (23°F), the Helium 400 offers reliable warmth for travel to more northerly latitudes and for early spring and autumn use at higher altitudes.

Choosing the right sleeping bag
A fitful night’s sleep is no preparation for the big day ahead. Sleeping bags can make the difference between a comfortable sleep and suffering through the night.
