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

It is excellent for winter hikes and other activities where you need a hydration bladder in frosty temperatures. In this high-quality hydration bladder, the taste of the liquid remains original, without unwanted aftertastes. The entire upper area of the backpack can be opened, making cleaning and drying easier. The backpack itself is not insulated, but the hose that hangs outside the backpack is insulated.
