You navigate freezing mountain nights with complete confidence using this 1500g duck down mummy bag specifically designed for serious cold weather expeditions.
Solid thermal retention: You trap radiating body heat efficiently with 1500 grams of premium duck down and a tightly woven 20D waterproof nylon outer, allowing you to rest comfortably when ambient temperatures drop toward -10°C.
Precision interior volume: You eliminate shoulder drafts and cramped positioning inside the 205 x 85 cm mummy chamber, which accommodates adults up to 1.8 meters while minimizing empty air pockets that waste energy.
Instant twin adaptation: You transform solo trips into shared campsites immediately, since the separate left-hand and right-hand zippers enable you to safely stitch two identical units side-by-side.
Optimized load management: You travel lighter on the trail carrying exactly 2.2 kilograms, and you easily roll this cold-rated system into a compact 43 x 23 x 23 cm volume that preserves critical pack space.
