It's the TransIt bag from performance: http://www.performancebike.com/shop/...tegory_ID=2312

Quality is nice, zippers are solid and it seems like it would be pretty water resistant. The mounting is a little awkward since you have to un-bungie both sides to get the thing off, although I haven't compared this to other bags.

It does a fairly good job of keeping my suit wrinkle free, but there seems to be a lot of wasted space. The small side/top pockets barely fit extraneous things like spare tubes, tools, towel, etc... And you can't really stick these items in with the suit. I'm thinking a big pannier may work better, with the clothes folded/rolled neatly on top.
