Easy, efficient drinking: The soft bite valve requires only light suction, so you can sip continuously while running, cycling, or hiking without stopping or removing your pack. Provides steady, ample hydration during activity. Compact, spacesaving design: The bladder stands upright when full for easy filling and shrinking to minimal volume as you drink, saving space in your pack and reducing sloshing. Durable construction: Built for longterm outdoor use with flexible tubing and a resilient bite valve for reliable performance on repeated outings. Compatibility and function: Designed for hydration systems used with backpacks and running vests. Serves as a convenient reservoir for outdoor sports and active lifestyles.
