With its lightweight materials and reversible, double-duty design, the Arête™ 18 is one of the most versatile packs we make. This bag gives you 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. We updated this version of the Arête with additional pockets to keep your gear organized, along with a removable sternum strap. The reservoir is not included. Use the code on the hangtag to get 20% off the reservoir.
