The Mammut Perform Fiber Bag -7C L is designed for users who want a dependable and comfortable sleeping bag for multi-day trekking, where low weight, packability, and sleeping comfort matter most. The manufacturer describes it as a sleeping bag for restorative sleep, featuring a newly developed shape designed to support a more natural and relaxed sleeping experience.
One of the key strengths of the model is its focus on comfort and climate control. The sleeping bag features a centrally placed 2-way zipper that allows intuitive temperature regulation, along with an insulated zipper cover designed to reduce cold spots. Extra comfort comes from the insulation chamber around the hood opening, the magnetic closure on the insulation collar, and the drawstring system for easy adjustment of the hood and collar.
Mammut also places strong emphasis on sleep quality. The soft material in the hood area is designed to reduce noise and increase comfort, while the bag comes with a deep sleep mask and earplugs to help reduce light and outside noise. The revised anatomical foot box offers greater comfort without adding unnecessary weight, and the internal pocket provides convenient storage for valuables.
The model uses Ajungilak synthetic polyester insulation, which the manufacturer describes as easy to care for and resistant to moisture. This makes the Perform Fiber Bag -7C L especially practical for mountain conditions where humidity and changing weather can affect sleeping comfort. The main fabric is made from polyamide, and the lining is made from 100% recycled polyester. The product carries bluesign® PRODUCT, PFC-free DWR, Fair Wear, and Recycled labels.
In size L, the model has a fill weight of 1103 g and a total weight of 1550 g without the stuff sack. Its comfort temperature according to EN 13537:2012 is -1°C, while the extreme temperature is -18°C. When compressed, it measures 29 cm in diameter and 32 cm in height, making it relatively compact to carry on multi-day hikes.
