This bag is awesome! Flap definitely stays shut on rough gravel/dirt tracks. It opens and secures easily. It is wide, and there is slight brushing with the legs when standing, but I no longer notice it. I carry iPhone 15, billfold, and many snacks in it. When stopping for coffee or breakfast, it goes in with me. Uses an excellent quick attachment system. Lots of thought and planning, and typical German first class manufacturing are apparent.
Pretty well built top tube bag. It's really handy to be able to quickly take the bag on and off and it snaps on with confidence. Don't know why quick-release for these types of bags are not more common. Pretty roomy inside, but I think the sides could be more rigid and more elastic or pockets inside would be nice since things tend to rattle around.
