Mammut Aenergy Pack

The vest-style design uses elasticized chest straps to pull the pack closer to your torso, which significantly reduces bouncing during high-output movement. It feels more like wearing a piece of apparel than carrying a traditional pack, making it ideal for fast-paced ascents.

Yes, the pack features large mesh shoulder pockets designed for quick access to hydration, snacks, or small essentials while you are on the move. Additionally, the back panel access allows you to reach your main gear without having to unpack everything from the top.

The dedicated front pocket is specifically engineered to house standard avalanche safety equipment, such as your shovel and probe, keeping them separated from your main gear for immediate access in an emergency.

Yes, it is versatile enough to handle both a speed attachment system for quick transitions and an A-Frame carry for more secure, traditional transport when the terrain gets technical.

The roll-top closure allows you to expand or compress the main compartment volume between 20 and 25 liters. This makes it easy to adjust the pack size based on whether you are carrying extra layers for a long day or keeping it minimal for a quick tour.

Yes, the Aenergy ST is hydration bladder compatible, allowing you to route a hose through the shoulder straps for easy drinking access without stopping.
