Nice Hunt!
Pros:
- nice camping gadget that allows you not to worry about your electrical devices running out of battery
- integrated battery with 3500mAh (about two full charges for your iPhone) lets you save up some for the night
- great design hiding all components and wires
Cons:
- being out in the nature a lot and wearing backpacks literally all day long I have to say I'm sceptic about it being comfortable wearing for a long time
