Arrio 18 Pack

About this find

The Gregory Arrio 18 Pack is a dependable choice for day hikes. Its suspended open-air mesh back panel lets air move between the pack and your back, so you can stay comfortable on the trail. The 18-liter main compartment gives you 1,098.4 cubic inches of room, and it opens from the top with a secure drawstring closure. You can also reach the main compartment through a panel opening.

The pack body is made of 210-denier Honeycomb CryptoRip HD nylon, and the bottom uses 420-denier high-density nylon. Both areas have a C0 durable water repellent finish, which helps shed light moisture. The pack has a total of three exterior pockets plus the main compartment, so you can keep small items within easy reach.

The perforated, breathable shoulder harness includes built-in hydration routing, and the sternum strap has an integrated safety whistle. Inside, a hydration sleeve with a SpeedClip hanger works with a Gregory QuickDry 3D Hydro Reservoir, which is sold separately. A front bungee system with reflective webbing loops gives you a handy place to attach extra gear, and the torso length adjusts to fit 16 to 21 inches.
