CamelBak Arete 18L Hydration Pack

What Our Gearhead® Experts Are Saying: "I love the versatility of the Arete 18. It’s light enough to stash inside a bigger pack for summit pushes but still functional as a daily hike bag. The 3D Vent Mesh carries surprisingly well, and the side stretch pockets fit bottles securely. Being able to swap the reservoir for a laptop makes it an awesome crossover pack for days when I’m hitting the trail before or after work." We reach for the CamelBak Arete 18L Hydration Pack when the day calls for speed, simplicity, and adaptability. CamelBak builds this pack with ultralight, compressible materials that let us transition smoothly from early-morning hikes to spontaneous afternoon detours. The 3D Vent Mesh harness keeps the carry cool and breathable, allowing us to move comfortably for miles whether we’re chasing summits or navigating a city commute. Thoughtful storage keeps essentials secure without weighing us down. The included 1. 5L Crux reservoir makes staying hydrated effortless, while the side stretch pockets expand to hold extra bottles or layers. A zippered phone pocket offers quick access, and the internal sleeve can safely store a 15-inch laptop when the reservoir isn’t in use. With its streamlined fit, airy comfort, and surprising versatility, the Arete 18 is built for days when adventure doesn’t wait.
