Hey man..!
Ah no I don't think they're the same ones. I found that link aswell and noticed the logo sticker is in a different place. Also, they don't have that black see thru pocket on the lids either.

But yeah- I'm starting to wonder if I need a slightly bigger capacity than the Backroller's 20L... hmmm...
Saying that- I have read that if you don't roll the tops down so much that you can get a little bit more capacity?
