For weekend treks or multi-day trips with light luggage, when comfort and optimal ventilation count above all, the Atmos AG 50 is your perfect companion. The AntiGravity back system takes any load off your shoulders and fits seamlessly to your back and hips thanks to the 3D stretch mesh. You'll be surprised if you actually carry everything with you. Your water bottles fit perfectly in the handy mesh side pockets, an internal hydration bladder pocket provides extra hydration, and the Stow-on-the-Go attachment system for trekking poles lets you stow your gear in a flash when you want to go hands-free. If the weather turns, protect your pack from getting wet with the integrated rain cover. Want to remove the floating lid? Thanks to the FlapJacket, the Atmos AG 50 can do without a lid. Don't compromise and experience your next big adventure with a world-class trekking backpack.
