I got an XL and that's the size I would normally wear. I just picked up the matching pants yesterday and those were very difficult to locate. Nobody seems to stock them and I didn't want to order them without trying them on. I finally located a dealer that had one pair in stock, and they were my size. I did a quick 500 mile round trip to pick them up yesterday. I thought I was going to go try them on and then order from Jenny, but the dealer gave me the discount and I was able to take them home with me. By the way, the jacket is great and I like everything about it except for one thing. The zipper gets stuck at the bottom all the time when I try to unzip it, because it has a double zipper(the 2nd one starts at the bottom and allows you to unzip from the bottom up). Other than that, it's one mighty comfortable jacket and I've found that I don't need my rain gear when I'm wearing it.
