The Atmos AG™ 50 is the best-fitting, most ventilated, and comfortable pack ever made for traditional backpacking trips lasting a weekend or more. The innovative AntiGravity™ suspension makes it feel like you're carrying less weight and seamlessly wraps around your body, which means you'll enjoy every mile more than ever. From easy-to-use stretch mesh side pockets, Stow-on-the-Go™ trekking pole attachment, and a FlapJacket™ for lidless use, the Atmos AG™ 50 is still the top contender.
