The CamelBak Cloud Walker 18 is described as a "simple, classic daypack perfect for hikes and less technical adventures." After testing, we agree with CamelBak's description. The pack's relatively substantial volume is fit for carrying extra layers, books, snacks, and water to get you through the day, wherever that may take you. Fine for moderate adventures, this pack isn't extremely technical, and if you pack it too full, there's no waist belt to distribute the weight from your shoulders to your hips.
The Cloud Walker is one of the larger capacity hydration packs in our gear lineup, comparable to the Osprey Skarab 18 in both capacity and function. The pack shares several similar features including a classic daypack style, single main compartment with hydration sleeve, and an included hydration system, but was edged out by the Skarab as our favorite large hiking hydration pack.
