Hydrapak Velocity It 2L Water Reservoir Clear, One Size

What Our Gearhead(R) Experts Are Saying:"This is my go-to reservoir when I know I'll be training or racing in the heat. The insulation really helps keep water cool and refreshing even on long runs, and the HydraFusion tube makes a noticeable difference. It's easy to fill, fits well in tight packs, and the bite valve seals perfectly every time."Whether we're hammering out trail miles or running under the sun, the Velocity IT 2L Water Reservoir helps us stay cool and hydrated from first step to final sprint. This insulated hydration reservoir is built with IsoBound(TM) technology to keep water colder, longer, while the wide slide-seal opening makes it easy to top off or toss in ice before heading out. A HydraFusion(TM) drink tube adds another layer of protection from the heat, and the low-profile design keeps the fit balanced and stable inside running vests and hydration packs. The bite valve locks with a simple twist, and the Plug-N-Play(TM) system makes refilling on the fly quick and clean. We love how easy it is to grab, hang, and drain-and we never leave for a summer run without it.
