As seat bags go, this one is beautiful. Well constructed, minimal profile w a very clean tailored look about it. I have the dual w the red piping.. Matches my bike perfectly and does not detract from the bikes racy profile. It's a tight fit around the seat rails, and would have liked a bit more Velcro strap to work with, but it stays in place even over tough roads. Very tight fit inside, if u intend to carry two tubes, levers and air. I personally could only fit one in there comfortably w all the other necessities. All in all, love the bag. If you pack the kitchen sink, perhaps not the right choice for you. If your bike has to look good and u are conservative w your necessities it's perfect!
