Equipped with a suspended, ventilated backpanel, the top-loading Gregory Arrio 18 day pack weighs just 1.4 pounds, provides 1000+ cubic inches of storage, and has a number of convenient, trail-ready features.
The pack's lightweight steel perimeter frame and trampoline-style FreeSpan suspension system delivers lightweight support while creating space between you and the pack to maximize airflow and create cross ventilation to keep you cool. Seamless construction, padded and contoured shoulder straps, and an adjustable sternum strap with a built-in safety whistle combine to aid in weight stabilization and enhance overall fit.
The lidded pack has traditional top access to the main compartment. A bungee system stashes discarded layers and allows you to lash other gear externally. There is also a zippered top stash pocket, a stretch side pocket, and a zippered side pocket. An internal sleeve and built-in hose pass-through make the pack hydration compatible (hydration system sold separately).
The Gregory Arrio 18day pack is available in your choice of colors.
