I was skeptical about the shirt never collecting odor, so when I got it I put it to the test. I am currently training for a Spartan Race and workout twice a day. I wore the shirt for a week without washing it, I know disgusting, but I wanted to get my money's worth. After a full test the shirt passed with flying colors! Can't wait to use these shirts for my backpacking trips where washing is limited, again nasty but if it works it works.
