Built for long miles, changing weather, and those spontaneous “might as well keep going” moments, the Gregory Arrio 28 Backpack is a lightweight day-hiking pack engineered to disappear on your back while keeping essential gear close at hand. With breathable suspension, trail-tuned organization, and flexible support that moves naturally with your body, the Arrio 28 strikes the sweet spot between minimalist efficiency and all-day comfort. Whether you're climbing steep switchbacks, cruising wooded singletrack, or stretching a quick hike into a full-day mission, this pack is ready to keep pace.
At the core of the Arrio 28 is Gregory’s VaporSpan suspension system, designed to maximize airflow without sacrificing support. The tensioned backpanel creates open space between your back and the pack for unrestricted ventilation, helping heat escape during warm-weather climbs and high-output movement. Paired with the CloudControl hipbelt and breathable perforated shoulder harness, the pack flexes naturally as you move, reducing hot spots and improving stability across uneven terrain. A lightweight perimeter wire frame adds structure and load support while maintaining a streamlined, agile feel on the trail.
Storage is intentionally organized for efficient movement and fast access on the go. The spacious main compartment handles layers, snacks, and extra trail gear, while the front zippered organization panel keeps smaller essentials easy to locate. Stretch mesh side pockets provide angled access to water bottles without slowing your stride, and the front shove-it pocket is perfect for stashing a rain shell or damp layers mid-hike. Trekking pole attachments, hydration compatibility, reflective attachment points, and comfort-focused details throughout make the Arrio 28 a versatile companion for everything from quick summit pushes to sunrise-to-sunset adventures.
