I was hoping for an upgrade from my Rain Shadow jacket. I live in rainy Southeast Alaska and water proof gear is very important to me. I'm 5'3, 115 pounds, petite build. Every Patagonia jacket I've owned has been an XS, however, the XS in this jacket digs into my pits. If it was just a little bit tight I would live with it, but it the way the seam digs right in is not something I could tolerate for more than a minute. It fit great everywhere else, but a little long and sleeves were long. I don't think the next size up would fit and I don't want to pay the extra postage to find out.
