Evecase iPhone armband case
I'm small (11 to 11.5 inch arm ) and this fits just perfect and if I keep working out like a bodybuilder it might not fit me anymore. It is not for swollen muscular arms for sure. Yet, I think I will maintain my arms to fit this as a guide to stop getting bigger arms. The screen does not interfere with the iPod and sometimes I just shake my arm to switch music (my iPad can do that).
