Material is like cotton, Fit is good. I like to work out in these.I bought the ones that seemed to be a little more narrow on the shoulder but not quite a tank top. The shoulder was wider then I expected.Either way a good fit and a good set of shirts for the gym.I like them but the material oils be a bit thickerUnless your arms look like buddy's in the photo, you might want to consider a tank top that's thinner at the traps like "Bruce Willis" Die Hard under shirts.The fabric is nice and light and very comfortable, kind of gives me a reason to work on my traps. They are what they say they are and all three of mine fit the same. Good product just wish the shoulder "strap" was thinner.They are softBought for average/lean 5'4 teen...men small just a little baggy. Good color variations. Would buy other color combos. Great price for 3 pack.Pics appear to make these shirts look closer to a tank top which was what I was going for, but instead they are closer to a sleeveless tee.These are great workout shirts. The size I ordered was consistent to the description and did not shrink after washing.All three tanks are nicely packaged and the fabric feels amazing. However, each one fit my husband completely different. One fit perfect, one was too snug, and one was in between. Make sure to check the size of the armholes too. Was kind of disappointed but thankfully they can be easily altered. I probably would not purchase again.
