I know that I’m an Amazon but am I really an extra large man?

So, being that I’m really excited about my upcoming kayak lessons, that I am opposed to wearing a stinky rental personal flotation device (PFD) and am going through serious shopping withdrawal (there are not too many places to shop in Yelloknife) I went to Overlander’s, the local outdoor store http://www.overlandersports.com to buy a PFD specifically designed for kayaking. The sales lady is a member of Somba k’e with me, so it was nice to see a friendly face- and the excitement built as I slept my arms in and started to do the zipper up. This is where the trouble began. I couldn’t get it done up around my chest… Christine has to loosen the straps off for me. Now here is my beef: Why do they call it unisex sizing? I think that it should be renamed “We don’t make women’s sizing” because unisex sizing is not cut for a female body it has the same cut as it would if it was designed specifically for men. I had to purchase a large/xlarge PFD. I do not think that I am the same size as an extra-large man, I believe that they should design PFDs to accommodate the female body!
Aside from the fact that it is a large/xlarge I’m very happy with my new PFD. It’s burnt orange, has a pocket, reflective stripes and a place to attack a knife. What more could a girl want?
