Baggy but cool.
True to size. A bit baggy but probably about as cool as any long pants can be in hot weather.

This shirt checked all the boxes, comfort, fit and feel.
Size: 3X-Large, Color: Teal 02, Size: 3X-Large, Color: Teal 02
OMG! what a nice shirt. The pattern is awesome and the material is very soft and light weight. It is so breathable. Material has a bit of stretch so it very comfortable sitting or standing and does not wrinkle. I will be ordering at least on more in another color
