The Flowlock Reservoir is a Nalgene-brand hydration system, featuring the Aquaguard anti-microbial treatment, a 90-degree high flow bite valve with an on/off system, tear-resistant thermo-plastic construction, a strong tubular design, and a lifetime warranty. Its quick-disconnect system allows you to separate the reservoir from the hose without spilling your precious liquid.

Available in 70 oz. (2 L) and 100 oz. (3 L) sizes. The Flowlock Reservoir is compatible with all Dakine snow and hydration packs, and its standard-sized Nalgene mouth opening works with most personal water filters.
