Aenergy ST 20-25L Backpack

Why We Like The Mammut Aenergy ST 20-25L Backpack

When it comes to short yet demanding tours, the Mammut Aenergy ST 20-25L Backpack is our top choice. This compact and body-hugging pack allows us to carry all the essentials with ease. With lash points for our ice tools and helmet, everything stays securely in place. Plus, the front zippered compartment helps us keep our avalanche gear organized and easily accessible.

One of the standout features of this backpack is its unique running-vest-inspired harness system. It provides a high and stable carry, ensuring maximum comfort even during challenging climbs. The stretch sternum straps allow our lungs to expand freely, making the final push to the summit a breeze.

What sets this backpack apart is its versatility. The roll-top closure allows for an adjustable capacity of 20 to 25 liters, accommodating varying loads. For convenient access to the main compartment, there's a back zipper. The front zipper compartment ensures the secure storage of avalanche equipment. Additionally, the backpack features attachment points for skis, ice axes, poles, ropes, and helmets, making it perfect for diverse outdoor adventures. The dual daisy chains enable us to lash on extra gear, while the mesh shoulder strap pockets provide convenient storage for snacks and a radio.
