This Jacket is Sick! I just received it in the mail the other day and already have gotten tons of good compliments on it. For me jackets are usually big around the waist but this one seems to fit perfect. Not too big and not too small. Also has good length to it. I would say whatever size shirt you are to go for that size. I got the Gingham Misty Fire and love it, Nice colors and has a bright look to it. Also the jacket has a super soft fleece type fabric on the inside. Would be a perfect jacket for spring riding for sure!
