Alforfun - I had to take my Collo off (oh no!) to measure it. And since I was wearing my Switchback over it, I had to take that off, too! For a moment, I had NO IBEX ON!!!! (horrors!)

Anyway, my large measured 24 inches from base of neck to bottom hem. The neck itself is 2 inches high. (so the entire back is 26 inches from top of neck to bottom hem) When I wear it the hem comes to the tops of my jeans pockets.
