The Aenergy 18 backpack from Mammut belongs to the series of the lightest hiking backpacks. You’ll get the most out of it on day hikes, but it’s also perfect for shorter exploratory trips in the surrounding area.
The reflective details are great for increasing your safety when moving in low visibility. Breathable and ergonomic shoulder straps and ample back padding ensure maximum comfort. The recycled materials used to make it are gentle on nature and the environment.
The storage space consists of a main compartment equipped with a hydration bladder pocket, a large mesh pocket suitable for a headband or documents, and two chest pockets suitable for storing energy snacks.
The roll-top closure is extremely practical, increasing the backpack’s volume by 2 liters when needed. So you can even pack a waterproof jacket or gloves.
