Using the Eberlestock G2 GUNSLINGER II backpack is a breeze. First, decide how you want to store your hydration. You can put two 3 - liter hydration kits in the side pockets or two 2 - liter bladders in the side - sleeves. If you need to use a radio, place it in the radio rack on the back wall of the upper chamber. The fold - down shelf is handy for organizing your gear, separating it into upper and lower sections. When it rains, simply unzip the bottom of the pack to deploy the removable raincover. As for maintenance, keep it clean by wiping it down with a damp cloth. Avoid exposing it to extreme heat or sharp objects. The polycarbonate frame is sturdy, but try not to put excessive weight on it to keep the shape intact. And that's it - with these simple steps, you can make the most of your Eberlestock backpack.
