This is a “Maverick” shirt - warm, cozy, merino wool blend that is very durable. Can be worn alone or as an over shirt. Pendleton does not make this shirt type any longer and it’s a real shame. It’s literally the best shirt they’ve ever made. I bought it for my child with sensory processing disorder who cannot tolerate jackets well, and it worked like a charm. Note that it’s tagged a medium but it’s really sized as a small. I bought it here and am selling it for about 1/2 what I paid for it. During my time, I’ve washed it cold and dried it laying flat two times. It’s in great condition because my child grew out of it pretty quick.
