Dad's first merino shirt

Dad got a long sleeve light grey merino protect shirt for his 75th birthday. He's quite active and does sweaty chores on the farm every day. I gave him the run down on how to care for and what merino does including thermoregulation and odor resistance and therefore you don't have to and shouldn't wash often. He said he would test that theory. Well, he Loves the shirt. It's his official pajama top so he wears it every day. This is high praise from this man. Thank you Merino Protect ❤️
