Filled with 261g of DOWN CODEX-approved duck down with a minimum 700-fill power and wrapped in a high-performance, 100% recycled Helium 20D outer fabric, the Helium 250 is a highly efficient, lightweight, and packable sleeping bag. Designed for warm-weather backpackers and tourers, it offers excellent insulation while keeping pack size to a minimum.

The slant-baffle construction enhances warmth, improves packability, and prevents down from shifting, ensuring consistent insulation and eliminating cold spots. A four-baffle footbox concentrates warmth around the feet, while the five-baffle hood optimizes comfort and ensures the down stays in place.

Inside, the 100% recycled Supersoft 20D lining fabric with Fluorocarbon-free DWR provides breathability and durability for long-lasting comfort. The full-length Gemini™ zip baffle significantly reduces heat loss and is reinforced to prevent snagging. A low-profile magnetic Lode Lock™ closure and easy-to-adjust collar drawcords enhance convenience, even in low light.

With a technical yet comfortable Alpine 2.0 fit, the Helium 250 maximizes thermal efficiency while keeping weight to a minimum. Featuring a Good Night’s Sleep Temperature of 1°C (34°F), it’s the ideal choice for warm-weather camping and backpacking.
