That appears to be a re-branding of the Infinit Solar backpack I bought last year.
The quality was terrible. One of the interior zips wouldn't close (the zipper moved, but the zip stayed open.), several of the seams have come apart and the solar cell was rubbish.
The battery would charge up, but would be flat again in less than a day. It seemed like the solar cell was draining it. I added adaptors to charge my PowerMonkey from the solar cell (It holds it charge perfectly well, normally) and that was flat a day later.
So I'd recommend you avoid this like the plague.
On the other hand, we bought a Wenger backpack for our accountant's birthday, a year ago and that is still a fantastic piece of kit. I think that'll be my next choice.
