Description

Mammut's Comfort Fiber Bag -15C L is a purpose-built mummy sleeping bag designed for hikers who need reliable warmth down to minus 15 degrees Celsius. Engineered with a newly developed shape, the bag wraps the body in a snug cocoon that promotes natural alignment and reduces tossing, helping you achieve restorative sleep even after a long day on the trail. The central 2-way zipper gives you instant control over ventilation. Open the top or bottom to release excess heat without compromising the overall insulation, so you stay comfortable whether the temperature rises at sunrise or drops after dark. Every component meets the rigorous EN ISO 23537-1:2016 standard, a benchmark for temperature rating, durability and safety in outdoor gear. This certification gives you confidence that the bag will perform consistently in demanding mountain environments. Mammut equipped the bag with an improved YKK zipper that slides smoothly and resists fabric jamming, ensuring quick entry and exit even when the bag is tightly packed. An insulated covering along the zipper eliminates cold bridges, keeping the interior temperature stable and reducing the need for extra layers. Choose the Comfort Fiber Bag -15C L for a blend of ergonomic design, precise climate control and certified performance, and enjoy a night's sleep that truly restores your energy for the next adventure.

Key Features

The bag's innovative mummy shape creates a snug, ergonomic cocoon that supports natural body alignment, helping you fall asleep faster and stay rested throughout cold nights.

A central 2-way zipper runs the length of the bag, letting you open or close both ends quickly, so you can fine-tune ventilation without breaking the thermal envelope.

Mammut tested this model according to EN ISO 23537-1:2016, ensuring the sleeping bag meets strict European standards for temperature rating, durability and safety in demanding outdoor conditions.

The upgraded YKK zipper features a smoother pull and reinforced teeth, which prevents the fabric from catching or jamming, giving you reliable access even when the bag is packed tight.

An insulated covering runs along the zipper line, blocking cold bridges and keeping warm air inside, so you stay comfortable without having to add extra layers inside the bag.
