It's a weird shirt.the material is nice and it fits snug around the mid-section, but the sleeves are large and it sort of looks like a shirt you've be wearing at a hospital. Not really scrubs, but similar. I'm 6'1", 160 lbs. Very lean with 15" biceps and the sleeves were still huge on me. I imagine some guy with my same build, but with biceps as big as his thighs would fit better in the shirt. I ended up buying a medium and it fit a little better. It's still a weird shirt, but whatever.
