Dakine 3L Vertical Reservoir 2. 0Got Water?A reservoir lives or dies by two things: how easy it is to fill and whether it holds its shape under load. The co-developed Dakine x Hydrapak construction addresses both. The fold-and-slide wide mouth opening makes topping off and cleaning a legitimate one-minute task rather than a pre-ride chore, and the low-profile Shape-Loc center baffle keeps the bladder from shifting as water volume drops - which means the pack rides the same at 100 oz as it does at 20. The Comet Bite Valve is self-sealing and locks open or closed with one hand, so you never have to reach back and fumble while navigating technical singletrack. The molded 3D bottom holds a consistent shape inside the pack sleeve and dries faster between rides. FDA-approved TPU construction keeps it BPA and PVC free, and a lifetime no-leak warranty backs every drop.
