The Dakine 2L 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 connecters make it easy to fill, drain, and clean. And, of course, it's BPA and PVC free.
