Mummy sleeping bag COCOON CMM35 — polyester, 60–80 cm width, 2200 mm length, blue

COCOON CMM35 is a mummy-style adult sleeping bag made from polyester, designed for compact packing and close-fitting thermal efficiency. With a minimum width of 60 cm and a maximum width of 80 cm, and a length of 2200 mm, this sleeping bag provides a narrow profile that reduces internal air volume for faster warming while remaining long enough for taller users. The product packs down to a compact package size of 150 × 95 mm, making it suitable for travel, backpacking and situations where low bulk and light weight are priorities. The polyester shell and inner surfaces are engineered to wick moisture away from the body, helping maintain a drier microclimate during sleep.

Advantages

The mummy cut concentrates insulation around the torso and head for improved heat retention compared with rectangular designs of the same material. Polyester construction offers quick-drying properties, light weight and resistance to stretching or shrinking when damp. The narrow width reduces excess air space, improving thermal efficiency while the long 2200 mm length accommodates a wide range of heights. The small packed dimensions allow easy attachment to packs or luggage and simplify storage when space is limited.

Suitable for

• Backpacking and multi-day hikes where low bulk is essential
• Lightweight travel and hostel stays requiring compact bedding
• Camping in mild to cool conditions when a close-fitting bag is preferred
• Overnight trips where quick drying after damp conditions is useful

Key specifications

• Shape: mummy-style for close fit and improved thermal performance
• Material: polyester shell and inner surfaces with moisture-wicking properties

How to use

Unroll the sleeping bag and allow it to air briefly before use to ensure the fill and fabric regain loft after storage. For best thermal performance, wear dry base layers and avoid trapping wet clothing inside the bag. Use the hood and any drawcords to reduce heat loss around the head and neck. After use, dry the sleeping bag thoroughly before rolling and packing to prevent moisture retention; if the bag becomes wet in the field, dry it as soon as possible to restore insulating properties.

Usage recommendations

Store the sleeping bag loosely in a dry, ventilated place when not in use and avoid compressing it for long periods to preserve loft and fabric performance. For colder conditions, pair the narrow mummy bag with a thermal liner or wear additional insulated layers.
