Comments: 6'1" 160 usually buy XL as they run kind of small, and they shrink if you dry them over time. Could go with a large though.

Comments: I'm 5'8" 160 and a medium is way too tight. Size up one unless you want it skin tight through the chest.

Comments: I'm in between a medium and large (5'9 at 157 lbs) and the medium is too snug.

Comments: These are nice singlets. I have bought 4 in different colors, size medium, I am 5'10" 150 lbs . Good price, wears well, nice fit with no problems.
