"Sweet shirt for Mainers. Flannel shirts - 24/7/365"
"Love my new Project Flannel. The cotton fabric stays soft after washing and keeps me warm. Normally wear a BD small. I noticed this was oversized so I ordered an XS and the fit is perfect. I get compliments all the time. Now I have a few colors. Thanks BD!"
