Thanks to GOAL ZERO`s solar panels and intelligent batteries, you no longer have to depend on the nearest power outlet, but you can actually produce your own electricity and take it with you. The Monowalker Fatmate is the ideal means of transport to transport the solar panels on top of the bag and to charge the Goal Zero battery during the day’s hike. With the batteries of Goal Zero you can spend days with camera or film camera through the wilderness and capture exciting moments, because with a Sherpa 100 or Sherpa 150 battery, you can always recharge its cameras. And on the Monowalker heavy batteries are stored in the side pockets on top of the wheel axle, without feeling their weight on the handles.
