It features 403g of minimum 700-fill power DOWN CODEX-approved duck down and a high-performance, 100% recycled Helium 20D outer fabric, ensuring optimal insulation without adding unnecessary weight. Despite its low weight, it provides ample warmth for chilly nights. The slant-baffle construction enhances heat retention, improves compressibility, and prevents down migration, delivering consistent warmth and eliminating cold spots. A four-baffle foot system concentrates insulation where it’s needed most, while the five-baffle hood ensures comfort and keeps the down securely in place. Inside, the 100% recycled Supersoft 20D lining with Fluorocarbon-free DWR enhances breathability and durability for long-lasting comfort. A full-length Gemini™ zip baffle minimizes heat loss while preventing snags, and the low-profile magnetic Lode Lock™ closure with collar drawcords allows for easy adjustments, even in the dark. Designed with a technical yet comfortable Alpine 2.0 fit, the Helium 400 maximizes thermal efficiency while keeping weight to a minimum. With a Good Night’s Sleep Temperature of -5°C (23°F), it offers reliable warmth for travel to cooler northern regions and early spring or autumn adventures at higher altitudes.
