I have a lightweight Sapper in XL. It was a disco'd model and I was happy to find one at the Orvis outlet for sub $200, especially since it was the exact model I wanted. In retrospect, a lg would have worked as well. I wear a 44 suit. Since the Sapper is a very casual jacket, it still works fine. The sleeves are a tad long but I roll them once so the corduroy is visible. In heavy rain, I unroll it. I'm now in the market for a beaufort and I've been trying to decide between 44 or 42. Both seem to fit well but i didnt try with a SC. Obviously, the 42 is slimmer, which I like. Just curious, do folks typically size down with the Beaufort/ Bedale?
