Well-built shirt that is comfort
"Well-built shirt that is comfort and durable. The fabric is thick and but isn't stiff. It has a rugged feel to it. fit's true to size with enough room for movement, and the stitching and buttons feel secure. Overall, great flannel!"
Comfy, warm, organic cotton
"Picked one of these up during the holiday sales. I prefer the non-heavy version as the heavy is a bit bulky and doesn't conform to the body as nicely. Also really hard to layer anything over this shirt. Overall though, it's comfy, warm, and 100% organic cotton."
Top Quality
"I purchased 2 of both of these. Both of them are heavy, super warm and top quality. I purchased 2 more of the crew neck in a different color, because I was so impressed with the quality. It was my first time purchasing anything from Black Diamind, and now I am a loyal customer."
Thick flannel
