The order form says that the Wind Shell Vest is Unisex sizing. But on the Voler site, the size chart for the wind shell vest shows mens and womens sizes.

Men's medium - Chest 38 to 40
Women's medium - Chest 34 to 36.

SadieKate -- What size wind vest do I wear? You told Voler that I would be the "problem" child, so I'm just trying to live up to my reputation.
