Superior 95% Goose Down Insulation

The 400g of 95% white goose down fill provides exceptional warmth without the weight penalty of synthetic insulation. Goose down offers the best warmth-to-weight ratio of any insulation material, creating thousands of tiny air pockets that trap body heat while remaining incredibly lightweight and compressible. This high fill power down lofts beautifully to create maximum insulation, keeping you warm in temperatures down to 0°C comfortably, with an extreme rating to -3°C.

Mummy Design for Maximum Warmth

The mummy-style shape (210 cm long, tapering from 80 cm at shoulders to 50 cm at feet) eliminates excess space and minimizes the air volume your body needs to heat. This efficient design reduces weight while maximizing thermal performance. The contoured hood with drawstring closure seals in warmth around your head and shoulders, preventing heat loss through the top of the bag where most warmth escapes.

Lightweight & Packable

At just 850g total weight, this sleeping bag is remarkably light for its warmth rating. It compresses down to an ultra-compact 28 × 17 cm, making it ideal for backpacking where pack space and weight are at a premium. The included compression sack allows you to pack the bag down tight, freeing up valuable space in your pack for other essential gear. When you need serious warmth without carrying heavy weight, goose down is the gold standard.

Durable Construction

The nylon outer shell provides excellent durability and resistance to abrasion from tent floors and rough use in the backcountry. The shell also offers some water resistance to protect the down fill from moisture. The soft polyester lining feels comfortable against your skin and helps wick moisture away from your body during the night.

3+ Season Performance

Designed for 3+ season use with a comfort range of 10°C to 0°C, this sleeping bag is ideal for spring, summer, autumn, and mild winter camping. The high loft goose down creates superior insulation that keeps you warm through cool nights in the mountains, during shoulder season trips, or at moderate altitudes. The extreme rating of 3°C to -3°C provides an additional safety margin for experienced users in colder conditions.

Care & Maintenance

• Store uncompressed in a large breathable storage sack to maintain loft
• Spot clean when possible to preserve down integrity
• When washing is necessary, use down-specific detergent
• Ensure thorough drying to prevent clumping and maintain insulation properties
• Never store compressed - this damages the down's loft over time
• Air out after each trip to remove moisture
• Professional down cleaning recommended for deep cleaning
