Looks great buy too short
Color: Red, Size: 4X-Large
Purchased for my son for a Christmas event at his job. He is 330pds and 6ft tall so I got the 4xl for him. It's fits perfectly in width BUT it's short. I know because he is tall I should have searched for a 4XLT but could not find one in the colors needed. But I purchased a white 4xlt tee for him to wear underneath and leave the shirt open it's looks great. So great shirt comfy and cozy well made and colors exactly as shown but if you are on the taller side maybe wear it as an over shirt with a tee underneath.

Well made, warm.
Color: Brown, Size: X-Large
A heavy yet soft flannel shirt. Nice on a foggy or light misty day. Flannel is a bit loosely woven but well sewn. Size reflects its lable. Its become a 'got to' shirt this fall.

Quality look
This is my second purchase of this shirt. Soft, thick, good quality. Usually worn open with a tee underneath. Sizing is normal and a good length. But it could also be tucked in. Looks great!

Great shirt
Color: Khaki, Size: XX-Large, Color: Khaki, Size: XX-Large
Wonderful shirt. Bought this for my husband to wear for family photos and it fit great, wasn't scratchy and he was so comfortable in it he actually wears it to work sometimes even to this day. I would buy this brand again. It washed it before he wore it, I didn't notice any shrinking.
