Velocity

Move efficiently with a hydration reservoir designed for running vests and compact performance packs. The HydraPak Velocity™ combines a narrow profile with a minimal, lightweight construction, helping it sit comfortably against the body without adding unnecessary bulk.

Choose the 1.5L size for shorter runs and smaller vests, or step up to the 2L version when you need more water between refills. An extra-wide Slide-Seal™ opening makes it easy to fill at home or at an aid station, while the soft grab tab helps you load and remove the reservoir quickly.

Key features

• Ultralight reservoir design: streamlined components keep pack weight low for running, cycling and fast-moving outdoor use.
• Slim profile: shaped to fit comfortably inside hydration vests and narrow reservoir sleeves.
• Soft grab tab: gives you a convenient point for carrying and for pulling the reservoir in or out of a pack.
• Universal hanger: works with common hooks, clips and loops used by brands such as Salomon, Nathan, Osprey and CamelBak.
• Wide Slide-Seal™ opening: simplifies filling, cleaning and adding ice.
• Comet™ bite valve: self-seals after each sip and can be locked one-handed when you want extra protection against leaks.
• Plug-N-Play™ connection: disconnects the drink tube for refilling or cleaning; an automatic shut-off helps keep water inside the reservoir.
• Reversible construction: turns inside out for more thorough washing and drying.
• Filter compatible: works with HydraPak’s 28 mm Filter Kit for backcountry water treatment.
• BPA- and PVC-free materials: built for regular hydration during training and outdoor activity.

Which size should you choose?

Velocity™ 1.5L

The lighter, shorter option for trail runs, races and compact hydration vests. It is a practical choice when refill points are available or when reducing carried weight matters most.

Velocity™ 2L

Provides an additional 500 ml for longer runs, warmer conditions, bike rides and routes with fewer opportunities to refill, while adding only a small amount of weight.

Recommended use cases

• Trail running and endurance training
• Race-day hydration vests
• Mountain biking and gravel cycling
• Fast hiking and lightweight day trips
• Activities requiring quick refills and a compact pack fit

Cleaning and care

1. Disconnect the drink tube using the Plug-N-Play™ fitting.
2. Open the Slide-Seal™ top and turn the reservoir inside out.
3. Place it on the top rack of a dishwasher or clean it with mild soap and warm water.
4. Rinse the tube and bite valve separately.
