## Long description

Thule 4157 Vital 3L Women's Alaska is a hydration pack designed for active women who need reliable, hands-free hydration on hikes, rides and day trips. The pack integrates a 3-litre reservoir with a female-specific harness and a lightweight construction that balances comfort and stability. It includes organised storage for small essentials and a hose routing system for easy access to water during movement.
Advantages
The female-specific fit reduces movement and improves load distribution across shoulders and back, while the 3 L reservoir supplies extended hydration without frequent refills.

Hose routing and quick-connect features enable straightforward refilling and cleaning.

How to use
Fill the 3 L reservoir with water using the refill opening, secure the closure, and place the reservoir into the designated sleeve inside the pack. Route the hose through the shoulder strap channel and secure the bite valve within easy reach. Adjust shoulder straps and sternum strap to achieve a snug, stable fit that minimises bouncing during activity. Refill as needed and detach the reservoir using quick-connect features for cleaning and drying after use.
Usage recommendations
