Ah.
To be fair, the only pac I saw with the nylon piece must have been damaged and home-rigged then because it definitely slid around on the strap. If that's not the legitimate case on the bags, then they look good!

I actually checked out the Bagaboo bags before buying this one. They looked pretty sweet honestly and in retrospect I feel as though I should have gone the route of one of their bags....

Do you have any experience with them?
