Fitment Note: For (P/N 830-393) T-Bags Route 66 bag.
It's exactly what it says, a replacement for the top net. I didn't get the top add-on roll bag with my T-bag, but I use it for holding my thermarest. I only needed to top net to hold the gear. It's a nice solution to the problem that looks good as well.
