I absolutely love these shirts. I play tennis in adult competitive leagues and I love wearing these shirts while playing much more than synthetic materials. They're light weight, dry quickly, and don't stink after I'm done playing! They also fit very well. I'm 5'10", weigh 220lbs and wear a large and it's very comfortable.
Disclaimer: they are very delicate! I have a couple of these t-shirts and polos and almost exclusively wear them when the weather permits. I snagged the shirts a few times on things like wooden benches and easily put holes in them. I'm ok with that and would patch them up and move along.
The only negative is after about a year of consistent wear, they really started to break down. Runs in the fabric, holes showing up, neck line starting to fray.
I barely ever wash them, maybe once a month in cold water. I never dry them in a machine, only air dry.
Almost any other product, if it started to break down after a year of use, I definitely would not be giving it a 4 start rating. These shirts are just so good, that I am ok buying new shirts yearly to replace them. I've actually started just ordering a shirt every 3-4 months so I always have newer ones to cycle through.
100% suggest the shirts, just don't expect them to hold up like cotton or other synthetics.
