Good but a little small
Color: Dark Grey, Size: Large
Seems worth its price, nothing fancy. It's tight in the shoulders but a size up would become too boxy in the waist for me. Didnt shrink too much so the size it arrives as should tell you.

Nice looking shirts.
Color: White, Size: Small
Fits well. It's a nice-looking shirt that can be worn on its own or layered over another shirt. It is somewhat thin, so it's more for milder weather.

Good quality

Nice quality and launders well. Not real warm, light weight flannel. Nice fit for me using normal order size.
