This solar backpack comes in green, gray, red, and camouflage. The soft solar panel is mounted in a flap that folds over the entire pack. I liked this bag's clean, functional design: The charging pocket is located on top of the pack, separate from the main compartment, so you don't have to worry about the bag's contents damaging your equipment. In direct sunshine a full charge took slightly less than three hours.
I liked the Juice Bag's smart design and fast-ish recharging. But for all three backpacks, unless you have to work for days in remote (and very sunny) spots, you're better off just taking extra batteries.
