Not to get too morbid but even if you’re name is Jeff Bezos, you’re going to die one day. We’re all get weak and old eventually so why not get strong while you still can?
We’re calling this design “fatally optimistic” because SURE, the world might end from nuclear annihilation at any point, death is a certainty but while we’re here, why not get absurdly strong? Why not push ourselves past our limits and make ourselves harder to kill?
Keep in mind the MAJOR difference in sizing is just the length (most tank sizes in the chest area fit pretty similar). At 5'10 and 180lb, I wear a size Large.
I would say the following sizes would work as a rule.
If you are below 5'4 (or female) get Small If you are between 5'5'-5'10 (and/or a small or medium build) get Medium If you are between 5'7-5'11 (and/or a medium+ build) get Large If you are between 5'9-6'1 (and/or have quite a lot of muscle) get X-Large If you are 6'0+ (until maximum height 6'5) get XXL
Women should wear the S or M. Most guys are either M or L (or if you are jacked/are taller, XL). Personally I like to wear the L or XL (whereas for t-shirts I usually wear a M or for leg day a L).
