The Hydrapak Reservoir is brimming with features. Here are some of the main ones -
Oversize slide opening lets you fill reservoir easily and quickly. Also great for dropping some ice cubes in.
The Snap-Zip Baffle on Hydrapak's Shape-Shift Reservoirs gives you all the benefits of a baffle (slim profile and reduced jostling), while still allowing you to reverse the system completely inside out. The baffle eliminates the sausage or scuba-tank feel, and let's the backpack's ventilation features work efficiently.
Plug-N-Play valve connector allows you to remove the hose without leakage which is great during cleaning and filling of the reservoir
36" Hydraflex tubing is softer and narrower meaning less kinking and better draping at the same time, but still delivering a big flow.
Quantum Clip uses a magnet to easily snap a high-flow drink tube in place along any point on the shoulder or sternum strap while riding, running, or hiking. See video.
No PVC used anywhere in the system
Hydrapak is the OEM supplier of reservoirs for major brands such as Shiman, North Face, Dakine and Salomon among others.
