Gregory Arrio 20 | Gregory

Designed for everyday trail miles, the Gregory Arrio 20 delivers a comfortable, well-ventilated carry in a compact 20-liter panel-loading pack that weighs under two pounds. The tensioned VaporSpan backpanel promotes airflow across the back even on warm Minnesota afternoons, while the flexing CloudControl hipbelt keeps the load stable without restricting stride. A breathable, perforated shoulder harness includes an integrated safety whistle on the sternum strap, a small but genuinely useful detail on longer treks. Inside, a SpeedClip-equipped hydration sleeve accepts Gregory's Hydro reservoirs directly, and an internal wire frame combined with trekking pole attachments makes this pack equally suited to a quick lakeside loop or a full day on the trail.
