This tank is damn good. Fits as expected but better, made of wool, doesn't stink. Unlike the best synthetic shirts, which last for weeks and then become unwearable, this shirt has stood the test of two days of heavy aerobic training, leaving it sweat-soaked and odor-free. I'm medium size, not large. It's 365 now, do some other colors! I tried a t-shirt from China, also made from merino wool, and the fit and finish of the 365 is significantly better than others. Sometimes a cassette isn't worth it.
