Hi, I just recieved my medium sized Icon timax jacket. and i'm not really sure how it is supposed to fit. It is perfect in the chest and the arms, which are supposed to fit between 38-40 inches, and 32 inches, respectively. However, the length from shoulder to waist seems a little short on me. I mean, it just barely comes to where my belt starts, and when i'm leaning in a riding position, it raises a tiny bit higher. I'm wondering if anyone can tell me if this is how this type of textle jacket is supposed to fit, or if i should try and get a large size. (large is 40-44 chest, 33 arms) and my measurements are 38-39 chest and 33 in the arms.) If anyone can let me know that'd be great, thanks, chris.
