I don't think they are available in shops, online only. I'm using underarm pads and find them, most of the time, very comfortable. I've figured that all depends on clothes you wear. If my shirt is solid, proper cotton, they do their job and you don't notice them. If I wear some light shirt, sometimes you can hear them, so in that respect you can call it uncomfortable. As I've been using them for a long time now I can say straight away if they gonna preform well.
