Mossy Rock is a very handsome green color. I bought about a dozen of these in various colors for work. These few didn't make it into my rotation so now I'm letting them go. Brand new with tags. These Filson Waffle Knit Thermal Crewneck Shirts are really heavy duty and easy to layer shirts for working and more. I wear them all the time.
