I have several Carhartt t-shirts and others, but the big Carhartt is a bit big. I'm 5ft 11in, 170lbs, waist 36in. I'm not a bodybuilder or body builder but I decided to try the medium because the size large fits my shoulders and I always had to tuck it into my pants. This new medium is the perfect size for me, not small. or big, so I call it "Smarge" and it fits perfectly. I can leave it unfilled, which makes concealed carry much easier, but it doesn't "print" to announce I'm armed. More orders
