Built for hot-weather training and long efforts, the Insulated 1.6 Liter Hydration Bladder features a low-profile, slosh-reducing design that keeps water colder longer thanks to its insulated construction. BPA-free with a high-flow bite valve, easy-fill opening, and quick-release hose for cleaning.
Compatible with most Nathan packs including Pinnacle Pro, Pinnacle Breeze, VaporAir, VaporAiress, and QuickStart 3.0.
