Lightweight and compact hydration pack for mountain biking.

The Katari sits high on your back and molds to your frame to ensure optimal comfort. With its 1.5 L capacity and enough stowing space for small essentials, you can focus on the ride.

For those speedy rides that require only the essentials, the Katari 1.5 is a perfect choice. This high-quality, slim-line design includes a 1.5-liter reservoir that can be slipped into its own pocket with a magnetically attached bite valve connected to a sternum strap for convenience. The well-ventilated mesh harness and curved soft edges of the shoulder straps ensure optimal comfort and stability while the tail light loop keeps you visible at nighttime. It was made with mountain bikers in mind but it is suitable for any situation where hydration is key.

  • Low-profile carry - When carrying water and a few essentials are all that’s needed, the Katari provides a lightweight option that rides close to your back for stability on any trail.
  • Reservoir included - An Osprey Hydraulics® LT 1.5L reservoir keeps you hydrated all day long and stores in an external hydration compartment to protect pack contents from accidental spills.
  • Ride stability - Our rolled, soft-edged harness contours to the upper shoulders to keep the pack close to your body and provide stability.
