I’m 5’9” and 185-190 lbs. Normally wear Large t-shirts. I thought I’d add a legit rash guard in the rotation from the Walmart compression shirt, so I bought the XL short sleeve rash guard. Just trained wearing the new gear for the first time tonight and they felt very comfortable. The shirt felt a little tight, but not uncomfortably so. The next size up might have been a little loose for my preference, but probably still acceptable. I’ve trained in Gold gis since the beginning and love them, and so far the nogi gear has impressed me!
