The jacket fits great for an off the shelf. The 46S is pretty true for me being an athletic build. It might be slightly large for some. The short is closer to a regular but for me was fine. Arms were about perfect. If you are a true Regular length you might be ok with the Short. Material looks very high end for a synthetic. It is slightly boxy in how it’s trimmed but again they are going for a general fit which it meets well.

Great Spring and Summer jacket! Lots of complements at the Regional Conv.
