I'm looking for a seat bag for my new rebuild, and would like some recommendations.

I want something large enough to toss a sweatshirt in for cooler days, and also some essentials for a longer ride. I don't want something too large that would require a (Bagman) type support. I was going to put a rack on the back, but I don't think I want to go that route.


This is what its going on.........
