One Planet Cocoon Sleeping Bag (-11M, -4F)

The Cocoon sleeping bag is ideal for light, fast adventures across seasons. It has an awesome warmth-to-weight ratio without compromising on comfort, a full and cosy hood, and a Storm Foot that adds waterproof, windproof and breathable fabric on the foot-box.

Bags in this series are available in three temperatures, with the lower limit of comfort for males/females -5/+1°C, -8/-2°C, -11/-4°C, all independently tested in accordance with ISO 23537-1. The Cocoon comes in small, regular and large sizes filled with 800-850 loft, non-PFC hydrophobic down. The 10-denier Vapour Vent V2 fabric used in the shell and lining is ‘downproof by construction’, offering exceptional breathability, water repellency and durability. The generous shape allows wriggle room, while the Vertical V baffles and a draught tube keep warmth in. The full-length YKK #5 locking zip opens from the foot for ventilation, while the anti-snag slider combines with our protective draft tube to stop jamming.

Features

• Box foot shape maximises the thermal efficiency of the Cocoon sleeping bag without restricting movement or comfort
