These shirts are fantastic. The neck isnt too snug or loose(like almost ALL undershirts seem to be!! Wtf?) These are thin but not too thin where you see your skin color through them. I work in the desert heat and cheap Birmingham City jerseys (supplemental resources) these help the most to keep me a bit cooler. Very happy I finally found undershirts that I like! I cannot believe how difficult it was to find something I didnt want to replace. Also, so far no staining on the pits etc like cotton and other fabrics do. Its still early on so not sure how they hold up with time but so far, very happy! Bought 5 to get through the week.

been a couple months now, many washes later and daily wear... I have no idea what people are complaining about with an odor but I have had zero issues at all! I hang dry mine after a wash using a small amount of detergent and vinegar together. I honestly only come back to update this because some of these reviews seriously came close to steering me away when these shirts have been my best find yet after many years of trying to find something I like that holds up. Should I need more, I wouldnt hesitate to buy these again!

the white shirts do tend to yellow and stain especially in the arm pits. Ive tried using heavy bleach and soaking etc and it just doesnt want to come out. I do love the shirts but the yellow staining definitely sucks. Trying darker colors soon
When I decided I wanted this workout shirt, I went to the reviews. I always wear an XL, but some warned to go with XXL. Reviewers say they are 5" 11 or 6' 3" and weigh x number of pounds and the XL fit perfectly. How important is that information really. Chest size is what makes the difference in a shirt size. I could not wait to inform those interested in this t shirt line, that my chest is 48 inches. I bought the XXL and it fit great. It is the same size as my large t shirts. Would fit a 46 inch chest loose, but comfortable. Would fit a 50 inch chest tight like a bike shirt. It is very light weight. I like the shirt and would recommend it to anyone wanting a very light weight shirt.
