Designed in collaboration with Hydrapak, the lightweight Nathan replacement bladder fits perfectly inside Nathan’s full line of hydration packs and running vests (sold separately) as well as most other branded packs.
The integrated bite valve has an excellent flow rate that makes on-the-go drinking easy. A fold-down closure opens wide to make it convenient to fill, empty and clean the reservoir and a sliding clip runs smoothly over the folded top to ensure that contents are safely stowed.
The Nathan Replacement Bladder is available in 1.5 and 2 Liter size options.
Sizes available: 1.5 Liters, 2 Liters
