Handling climbing gear

When googling around yesterday I found this thing called a Trad Rollup, which seems to be a great way to get all the gear to and back from the cliff without causing a mess in the backpack. The question is if anyone knows where one can buy one of these Trad Rollups?

The California Roll is an alternative though we don’t have nearly enough gear for such a big thing and it’s more expensive as well. But still, anything is better than the mess we have now. Unfortunately I have no idea from where to get one of those either.
