When the Helix Floor was originally released they included the backpack in an introductory bundle. I wasn't impressed with the build or materials; I have some very nice backpacks and bags that I compared them to. IMO, they were so-so, and unless they've greatly improved the quality for the price, I'd go with something by Studio Slips.
But that seems to be the situation too often; Some company makes a product and offers a bag for it, slaps their logo on it, but forgets to put the quality in.
Jeez, I sound like a curmudgeon.
