    I needed a bag that would sit on the top tube of my road bike with enough room for my cell phone and misc items. I wanted it slim so my knees would not hit it and stable when it comes to side to side movement. This bag fits that niche very well. It has just enough room for my cell phone, ID, lip balm, energy bars, and a pack of goo. The magnetic enclosure is nice and works well. Since the top is mesh I carry a plastic bag for my cell phone in case of rain. When riding hard out of the saddle there is a bit of side to side slop but not enough to be troublesome. All in all this is the best bag I could find to fit my needs.

    Perfect size, well made and good function, if you have to carry a few small items on top of what’s in your seat bag this is a darn good choice. I got the bag specifically for my cell phone but there’s also enough room for a variety of additional items within reason. The only concern is the side-to-side flop, which isn’t a rally killer, but I don’t like it personally; so I think the remedy is to attach/sew an extra Velcro strap on top of the existing strap and the bag will be solid. And actually (at least on my bike) there’s enough extra Velcro on the bag that I can probably cut and sew an extra strap on top of the existing one. Either way it’s a good bag, and the sticker shock is far outweighed by the appearance functionality.
