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 Arête 18. With its lightweight materials and reversible, double-duty design, the Arête 18 is one of the most versatile packs CamelBak makes — perfect for summit hikes, backpacking trips and travel. When you’re not wearing it, it transforms into an insulated reservoir sleeve—ideal for holding your water supply steady inside a larger pack. Ready for a quick hike? Just flip it inside out, and you’ve got room for snacks, layers, essentials, and 1.5 liters of water. Its lightweight materials and packable design also make it an excellent travel bag that won’t add bulk to your luggage.
