Mammut ASP Down Winter Sleeping Bag

The Mammut ASP Down Winter is a lightweight mummy sleeping bag with down insulation, designed for multi-day hikes and ski touring. It suits users who need a high warmth-to-pack-volume ratio and value stretch knee panels for greater freedom of movement.

Key features

• Premium 90/10 down filling offers thermal insulation with low packed volume.
• 700 cuin fill power provides efficient warmth at reduced weight.
• Stretch inserts at the knees improve comfort for side sleeping and bent-leg positions.
• Anatomical insulating collar and adjustable hood reduce heat loss around the head and neck.
• Option to fit an anti-snag YKK zipper slider to minimise fabric catches.

Suitable for 3-season to winter use on multi-day mountain routes and ski tours where the balance of warmth, comfort and small packed size is required.
