With its lightweight materials and reversible, double-duty design, the Arete 18 is one of the most versatile packs CamelBak makes. When you’re not wearing it, it reverses into an insulated reservoir sleeve—perfect for holding your water supply steady inside a larger pack. Ready for a quick hike? Just flip it right side 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. This version of the Arete is updated with additional pockets to keep your gear organized, along with a removable sternum strap.
