“I’m 174cm / 65kgs. Wide shoulders with an approx. inseam 78cm and 90cm chest. At first, I thought it would be way too small when i took it out the package, but it actually fits very nicely! A perfect snug aero fit. Definitely size up if you want a club fit / less form-fitting. The sizes up aren’t a drastic change, they are both still snug. You will just have slightly longer length at the front with M and more room under your pits, etc. If you weigh around the same as I me but have a huge torso, go M. Don’t usually go out my way review products but the quality was so neat, I want to let others know how impressed I am! Well done, MAAP.”
