Just received as a Christmas gift and I was lucky to get to pick color and based on the vague sizing listed in the size charts assumed a medium would work since I'm 6'0" 175 and a classic medium in todays sizing and rarely have issues when selecting a medium. Plus quite a few reviews stating sizing was right on. But I should add I noticed the model pics hinted at longish, bunched sleeves. Well, the medium I received has that and more. The sleeves are easily 5" too long and come down to my finger tips. The sleeve seams are a touch over the shoulder but about right and okay. The body/chest area with my 39.5" chest feels a bit loose. So, here I am, with my sleeves rolled up 3x to achieve 1.5" cuffs on each TOO LONG sleeve as I write this review. I should've paid a little more attention to the full-hassle-you-pay-too-return-policy and the suspicious sleeves in the product images where the size chart cleverly avoids tell you the sleeve length. If I exchange for the small on my dime, I'd still have sleeves too long, so I guess I'll stick with this one. But buyers beware. I'm shocked so many reviews say fit is okay. The sleeves are ridiculous.
