This shirt made of functional material is very light and comfortable. It would be great to pack for travel as the material is very light. I prefer this type of material for all outdoor activities as it breathes very well. I'm 6ft 0in, 230lbs, size XL fits perfectly. This is a great golf shirt as it allows you to move/rotate without material binding and it keeps its shape. There are a few odd pockets (like you can put a pen in) on the shoulder which I'm not sure are useful.
