Description

The Aenergy ST 20-25 White/Black rucksack from Mammut is a unisex model that will accompany you on your most ambitious ski touring outings.

It has been designed to be as comfortable and practical as possible. The chest strap is elasticated for a perfect fit, and the CONTACT carrying system, inspired by trail-running jackets, distributes the weight evenly across the back for maximum comfort. Its front compression element can be removed for use as a waist belt. Naturally, this bag is compatible with a hydration system. The Aenergy ST has a roll-top zip to prevent accidental opening. Its PFC-free water-repellent treatment means your gear won't get wet or snowy.

On the practical side, this technical backpack has a number of pockets that are easily accessible at a touch of a button, thanks in particular to the large zipped opening on the back. Large mesh pockets on the shoulder straps keep small personal items such as a hat or glasses case close at hand. It has a helmet holder and a front pocket dedicated to avalanche safety equipment. For the steepest parts of your outings or at the end of your session, you can hang your skis on them.

Bluesign® The bluesign® system is the solution for an environmentally friendly textile industry. It eliminates harmful substances from the beginning of the manufacturing process and sets and monitors standards for safe and eco-friendly production.
DWR The durable water repellent (DWR) finish repels light rain and snow and reduces the drying time of the fabric. In addition to the waterproof/breathable membrane, the DWR treatment prevents the fabric from becoming saturated with moisture, so that the breathable membrane can function properly.
