I clicked on the link for sizing information and it stated a size medium was a 12/14, so that's what I ordered.  My son wears a size 10, but is outgrowing that size so I went with the 12/14.  However, when the jacket came it was a size 10/12.  It still fits him, but not sure if we'll get two winters out of it due to sleeve length.

That being said, this is a thick, warm jacket and should suffice for a cold midwest winter.  The olive color as shown does not represent the actual color (It's a darker olive, not tan, which is what I was hoping for.)  Detachable hood is a bonus, since weather doesn't always necessitate the need for a hood.  Snaps on pockets seem a little cheap, not sure if they'll hold up with repeated use; time will tell.

Overall I can't complain since we got this on sale at Amazon for thirty eight dollars.  Can't go wrong with that.
