For us the perfect tee must have several key elements: Great fit, soft, durable, American grown natural fiber and effortlessly look great no matter how you style it. At 8oz this is no light weight. Not see through, even when wet. True to size with a tailored shoulder and arm and a bit of extra length in the body. Wear your normal size for a tailored fit or you can size up for a more relaxed fit. We knit this shirt to have a bit more weight and structure to improve the drape and ensure a flattering fit.
