Although I am not a giant (5'10, 165 lbs), I think I would have to be to fit into this flannel. It is unfortunate because I previously had an insulated North Face flannel that I EXTREMELY loved (the fort point flannel when it had insanely awesome colors)...but I was an idiot and ripped it. I digress. I got this flannel in a small and when I put it on I was shocked. I thought darn...you did it again...you bought an XL on accident. I looked at the tag to confirm my sneaking suspicion only to see five little letters. Small. In all my rage I ripped off the flannel and sent it back to BC. Until next time North Face.
