Why We Like The Mammut Aenergy 18L Daypack

When going for a record car-to-car time, we load the essentials in Mammut's Aenergy 18L Daypack. The running-vest-inspired shoulder straps feature 2 pockets to stow soft flasks for handy hydration that won't slow us down, while the lightly padded back panel keeps our carry comfy, not weighted. As the trail steepens and our pace quickens, the bungee sternum strap stretches with our breathing, letting our lungs expand freely. In addition to a speed-minded design, this pack features a partially recycled construction that keeps our carbon footprint light.

High Speed, low drag

The Mammut Aenergy 18 backpack is extremely versatile and exceptional. The light-weight yet durable and comfortability make it an awesome choice for 20 mile through hikes to climbing small mountains. It’s great for people looking for an everyday around town backpack or someone looking to conquer the single day or overnighter outdoor adventure. The roll top part of the backpack offers a very wide range of gear storage while still being a light weight and fast backpack. I have ran, hiked and climbed with this backpack and it has done it all.
