I'm 5'11" and 160 pounds. I have a 40" chest. Based on the size chart I ordered a Medium that showed a 46" chest. It's tight round the chest. The idea that I can have a cap under the top doesn't work either since it pulls on the entire jacket. Other than size the rest was great, never tried the pants though. I't going back and I ordered and XL so that should do it. I'd say based on the look the pants would be a fit with a larger than needed waist in the Medium. But it's an 'outfit' so all went back an hour after I got it. Overall good construction for the price. Watch the size though!
