im picky about tshirts. im 6'1 170 lbs and no shirts are ever long enough. i like a fitted shirt. these are by far the best tshirts in the world. they have lots of length (not too much) great fit. perfect tightness around arms. sleeve length comes to mid bicep (and i have long arms) i wear mediums because i like a regular cut fit and these are perfect. doesnt shrink down in the wash like most others. nice and soft material. perfect shirt for the tshirt enthusiast. wear em by themselves
