Backpack Gregory ARRIO 24 — 24 L internal-frame trekking pack, nylon, black

Gregory ARRIO 24 is a 24‑liter trekking backpack with an internal frame, ventilated back padding and lightweight nylon construction. Weighing 760 g and 270 mm wide, the pack is designed for day hikes and fastpacking where organized storage, comfortable carry and easy access to essentials are priorities. The design includes a suspended open‑air mesh backpanel for ventilation, a perforated shoulder harness with hydration routing, multiple quick‑access pockets and a built‑in hydration attachment system. A custom fitted raincover and reflective details increase utility in variable weather and low light.

Advantages

The ARRIO 24 offers a ventilated suspension system that helps reduce heat buildup against the back, paired with a breathable shoulder harness that routes hydration tubing and integrates a sternum strap with a safety whistle. Multiple pockets and attachment points provide organized storage for small items, while side stretch mesh and zippered stash pockets allow immediate access. The internal frame and ergonomic shape distribute load for comfortable day use, and included raincover and reflective webbing enhance functionality in wet or dim conditions.

Suitable for

• Day hikes and short trekking trips
• Fastpacking and lightweight overnight outings

How to use

Load heavier items close to your back and center them to maintain balance. Place hydration reservoir in the internal sleeve and secure it with the SpeedClip‑style hanger, then route the drinking tube through the harness channel and fasten the sternum strap at comfortable height. Use the top zippered pocket and side stash pockets for frequently needed items and the front bungee for lightweight outer layers. Adjust the hipbelt and shoulder straps to distribute weight across hips and shoulders for longer wear.

Usage recommendations

For optimal comfort on warm days, keep airflow by not overpacking against the ventilated backpanel. Use the raincover in wet conditions and reflective webbing for improved visibility. Choose a compatible 3D Hydro/quick‑dry reservoir to maximize hydration performance (reservoir sold separately).
