Although I'm not exactly sure what to put in the small pouches, they don't fit a pair of glasses, the middle pouch is a good size. I'm happy with the look and glad it doesn't protrude beyond the fairing.
I like these pockets. I've been using them for about four years now and they are quite convenient. The only complaint that I have is that the latches will rotate and the pockets open, if they are not locked shut. I used a couple of large snap links for fishing lures, to clip through the locking holes. This doesn't let the pockets open while riding. But, all in all, these are great pockets for small items like a phone, wallet, tire gauge, Easypass for toll roads, etc.
