Query: not for small arms!

The skin is great - I plan on keeping it on my nano for travel and any other use, regardless of the armband... which won't be a problem since the tightest I can wrap it is still not adequate for my upper arm. I've not had problems with getting a snug fit from any other armband in the past (I guess my arm's somewhat small, but definitely not abnormally so), so I was dissappointed in this one.. have to switch it out with an old one that I've been using, which is really gross at this point. :)
