The backpack fits torso lengths ranging from 17-19. 5 inches, and carries up to 25 pounds of gear. The contoured shoulder straps and hip-belt support your load, and are padded with mesh-covered foam for enhanced comfort and breathability. The backpack is compatible with your hydration reservoir, and includes a reflective attachment for your drinking tube so you can easily find it if you're out on the trail before sunrise or after sundown. Stick items you'd like quick access to in the mesh side pockets and store valuables in the protected zippered lid pocket. Attach tools or carabiners to loops on the lid, and slide your hiking poles through the side pole attachment loop. When you reach a scenic peak that makes a good lunch spot, open up the front panel for easy access to your food and supplies.
