Hey guys, I wanna get a Nike+ Forearm Compression Sleeve for my iPhone 4s. Do you have any experiences with it? I'm also not sure about what size to buy, I would be happy about any help. On amazon are different reviews, but one says the s/m size is really small and the l/xl for a monkey. Another one says the s/m size is goot for not that muscular forearms. I'm 180 cm tall an weight 71kg. I have normals arms.. Not pretty muscular and not that skinny.
