I've been contemplating a new pair of breathables myself.
After studying all of the size charts, I have come to
the conclusion that, of the dimensions listed (shoe size,
inseam, and chest,) I can match exactly two out of three.
I've given up on mail order, and will wait till I can
get to a shop where I can try them on and see which
one fits halfways decently.

Kevin,
13,35,and 44, if you were wondering.
