Osprey Katari 7L men's hydration backpack with 2.5L reservoir. When the name of the game is keeping hydrated, Katari is the ideal pack to carry. Built with a focussed feature-set and performance-based shape, this pack is made to move with you during warm weather activities. Housing an integrated 2.5L Hydraulics LT reservoir while retaining a great fit and comfort, these packs help to push your limits. A small, streamlined design and stable fit keeps your water where you need it, even when your movement speeds up. An innovative, ventilated mesh harness, back-panel and webbing hipbelt lock the pack down to your back, while the bite-valve is always within reach thanks to the innovative magnetic sternum strap, which can be opened and closed with one hand, while never taking your eyes off the trail. The front vertical-zip pocket gives easy access into an organiser for your essentials, be they bike tools or trail snacks. A top scratch-free pocket can store your sunglasses or phone without risk of damage, as well as a separated pouch and clip for your keys. The LED light attachment point and reflective graphics can give you peace of mind in darker conditions.
