The website is quite confusing on the products.  The womens' & mens' are all in the same web site.  I bought one for myself and another one for my husband and that's how I found out the difference.  If there is a zipper near the Marmot logo, then it is a man.  The woman jacket has only side pockets.  The man's is more boxy look but the woman's has a shape to it.

I bought a woman's Team Red (it's a VERY bright red colour), size S.  Measurements:
inner armpit to the bottom of the jacket :17"
inner left armpit to inner right armpit: 20"
inner armpit to the end of the sleeve: 21.5"

A man's black, size L.  Measurements:
inner armpit to the bottom of the jacket length:18"
inner left armpit to inner right armpit: 24"
inner armpit to the end of the sleeve: 23"

I hope this helps.
