CamelBak Arete 18 Hydration Pack

{{ vm.state.webThumbOverlay.code }}


A minimalist ultra-light hydration pack for the final ascent or reservoir sleeve to throw in a larger multi-day pack – you get both with the Arete 18.

Convert the Arete into a reservoir sleeve and place in your larger pack to be your hydration solution as you trek to basecamp. When you're ready to go for the summit, convert it back to its pack form and pack your summit essentials, such as headlamp, trail map, shed layer and food.

The two-litre Antidote hydration system also folds into its own pint-size pouch so you can stash it in your backpack.

Man running with CamelBak gear.

CamelBak emerged out of the simple desire to find a hands-free solution to hydrating on the go.


Originally made from an IV bag and a sports sock, the first CamelBak was developed by cycling enthusiast Michael Eidson during a gruelling 100 mile race through the Texan summer. From that moment of innovation, CamelBak was born, and since then has grown into a range of water bottles, hydration packs, reservoirs and accessories; helping you to stay effectively hydrated and safe when working hard.
