HydraPak Hydration Reservoir Velocity 1.5L bladder, gray

The HydraPak Hydration Reservoir Velocity 1.5L bladder in gray is a lightweight, soft hydration reservoir designed for hands-free drinking during outdoor activities. With a 1.5‑liter capacity, the Velocity bladder stores sufficient water for running, cycling, hiking or daily use. Constructed from flexible TPU material, it is compatible with most standard hydration packs and features a wide-fill opening to simplify refills and cleaning while maintaining a secure closure for leak-free transport.

Advantages

The flexible TPU construction keeps the bladder lightweight and durable while resisting odors and stains. The wide-fill opening allows quick refills from bottles or taps and provides easy access for thorough cleaning and drying. A secure closure system ensures reliable leak protection during dynamic activities, and the low-profile shape fits comfortably in many pack sleeves. The neutral gray color integrates unobtrusively with outdoor gear.

Suitable for

• Trail running and road running where hands-free hydration is needed

How to use

Open the wide-fill opening, fill the bladder with potable water up to the recommended capacity, and secure the closure according to the closure type. Insert the bladder into the hydration sleeve of your pack, route the drinking tube through the pack’s hose port, and attach the bite valve to the tube. To drink, bite the valve and draw water through the hose; when not in use, close the valve to prevent dripping. After use, fully drain the reservoir, open the wide-fill for cleaning, rinse with mild soap and warm water, and allow to air dry completely before storage to prevent mold growth.

Usage recommendations

For best results, use clean potable water and rinse the bladder after each use. Dry thoroughly and store with the cap or closure open in a cool, dry place. Avoid prolonged exposure to direct sunlight and to liquids with sugars or electrolytes without rinsing promptly, as residues can promote bacterial growth and shorten the life of the TPU material.
