Although somewhat hesitant to order these shirts due to the lack of sizes to choose from, I did order them based on comments in the reviews. I'm glad I did! There was no size information on the package or the actual shirts themselves, but they fit me just fine. I would have ordered an XL as I'm 6' 4" and around 195. They have adequate length to keep them from riding up, and the fabric is most comfortable. I was glad to find them; had been looking for sometime for a replacement for my sleeveless, V neck Murano brand Ts. They are tight fitting, but that is what i like. If you're about my size and looking for loose fitting Ts, don't order these. l
