The Soular Powers packs from Neon Green aren't quite fully cooked - we don't know prices or availability, making their casually announced line a bit tough to follow. But they're bold, practical and, above all else, unabashedly solar.
We believe the lead shot is the Capsoul, a 3-in-1 backpack. Its solar panel is removable, and the entire bag can be reconfigured to both a smaller shoulder bag and carrying case.
There's also the Piggy Back, which is much smaller, and can attach to your existing bag. Neon Green promises 11.1 volts from the Piggy Back in full sunlight, which I assume means the Capsoul produces even more power.
