Cool, comfy for hot days

The shirt arrived quickly and fit me perfectly. I'm 73 inches tall, slender and ordered the large. The shirt is perfect for warm weather. The material is a good quality. I'm not sure it will held my golf score, but it looks good wearing it.

Cute design. Seem to be well made. Super thin fabric though. Time will tell..
Color: Black Golf, Size: Large
Really cute design. One thing I noticed immediately is that the fabric is super thin. I wonder how many washing before they tear?
