3L Vertical Reservoir
The Dakine 3L Hydrapak design of the Replacement Reservoir is engineered to be durable and easy use.
The Shape-Loc center baffle adds some rigidity to the shape of the bladder, which cuts down on shifting of water weight while you're in motion, and makes for a more resilient design.
While the wide mouth opening and plug-and-play connectors make it easy to fill, drain, and clean.
And, of course, it's BPA and PVC free.
