The ALPS Mountaineering Hydro Trail 17 is a versatile hydration pack designed to support high‑movement activities such as cycling, running, hiking, and climbing while maintaining quick access to water and essential gear. Built with lightweight 200D nylon double ripstop fabric, the pack balances durability with comfort and weighs approximately 2 pounds 2 ounces. A suspended mesh back panel improves airflow and breathability, helping reduce heat buildup during extended use. Total capacity measures 17 liters, or about 1,038 cubic inches, providing ample space without excess bulk.

The pack includes a 3‑liter ALPS hydration reservoir and features a large main compartment, front organizer pocket, stretch side pockets, trekking pole loops, and side compression straps to stabilize loads. Reflective details enhance visibility in low‑light conditions, and a removable sternum strap allows fit customization. A built‑in rain cover is neatly stored in a zippered bottom pocket and deploys quickly when weather changes. Designed as an all‑in‑one hydration and gear solution, the Hydro Trail 17 delivers efficient storage, comfort, and reliable hydration access for active outdoor pursuits.
