Description

Nearly a pound lighter than the Exos 58 and featuring a more fine-tuned adjustment system, the 55-litre Exos Pro is the most comfortable ultralight thru-hike backpack in its weight class. A highly-ventilated AirSpeed™ backpanel supports light loads with ease while maintaining maximum airflow across your back, making it an ideal pack for your most long-distance endeavours on the Appalachian Trail, Tour Du Mont Blanc and beyond.

Features

Large front fabric compression pocket with stretch side panels accommodates overloads
Multiple front panel lash points for securing extra gear
