I have the high performance Velcro short binder and the 2nd gen jersey mesh. As far as comfort goes, if you don't do the Velcro super tight, the high performance is quite nice. It's made of this silky smooth material, almost like swimsuit or under armour. It's very good at wicking sweat. The jersey mesh, I found to get sweaty and gross easily because its made of a cotton material. I also felt like my chest was going to fall out the bottom of the jersey mesh. I'm a B cup though, so you might be okay. The biggest problem I have with the high performance is that the binding material doesn't come up high enough on the chest, like the shoulder straps are too long. This might be an easy fix if you can sew. I've also seen very good reviews of the sports pullover binder by smaller chested guys. My best advice is to check out the comparison chart on their site and read the reviews on there for each binder. Good luck!!
