Evoc hydration bladder insulated is an insulated hydration pack that keeps drinks cool in the summer and drinkable in the winter. The hose of the hydration bladder has neoprene insulation that prevents the liquid from freezing or heating up. Additionally, the mouthpiece features extra insulation. A tip is to blow the liquid back into the pack if you want to ensure the hose remains open in severe frost conditions. Compared to the previous model, this pack has an easier-to-open bladder closure and a more user-friendly mouthpiece closure.

It is excellent for winter hiking and other activities where you use a hydration bladder in freezing temperatures. In this high-quality hydration bladder, the taste of the liquid remains original without any off-flavors. The entire top section of the pack opens, making cleaning and drying easy. The pack itself is not insulated, but the hose, which is exposed outside of the backpack, is insulated.
