Amazon EssentialsMen's Long-Sleeve Flannel Shirt (Available in Big & Tall)

Is this shirt pre-shrunk, or does it shrink in a washer/dryer?

What is the weight of the cloth used for this shirt? I realize the item weighs 12oz., but I was curious about the thickness of this shirt. Thanks

I’m 5’5’’ and around 138 pounds with a slim body. What size should do ya recommend?
