Dave Watsonwrote a review of CamelBak Arete 18 Hydration Backpack - 1100cu in on August 26, 2016
Familiarity: I've used it once or twice and have initial impressions
Awesome hydration pack. Super light weight and packs down very well. I like it for traveling because I can fold it up and put it in my duffel bag. It kills 2 birds with one stone- practical day pack and water bottle in one. You can store my jacket or two, keys, wallet, and more. The quality is good and I did not find any defects.
