Shirts great, shorts are see through
Color: White, Size: Large
So my husband loved the shirt. It looked great on. However, the shorts were of a weirdly thinner material and completely see through. You could see his underwear right through the shorts.

Quality shirt
Color: Angel Falls, Size: XX-Large
Great quality fabric , style, and fit. My husband loves the fabric and colors. Ordered his normal xl but too tight across his stomach so returned and sized up , and fits much better. Even sizing up the shoulders hang nicely . He likes so much ordered two colors, both great.
