"I have at least four of these project flannels in both weights. Great flannels."
"I have yet to meet a Black Diamond flannel that I don’t like and this one is no exception."
"Haha Well, my wife didn't want it, but it fits me! Will be cold wash and hang dry. Nice flannel. Color is great. Once I start wearing it, her mind will change. LoL"
"I love this shirt, its my go to for cool days in the mountains. Its so warm and cozy. The sizing is on point!"
"I ordered one size up due to the reviews. Sadly, I found it true to size (even after a wash) and am unable to return or exchange it for my proper size (I purchased it on sale). I really like how soft it is. It's also thick and sturdy. Would recommend, in ones appropriate size."
"I love this soft and cozy flannel. I bought the medium (I'm normally a small in outerwear) and it's a little big but that is how I wanted it to fit. I can wear it over a baselayer. The mustard color is really lovely as well!"
"5'6' 165lb. Love the mustard color. Cozy and soft, I should have ordered a size up though for a more baggy/ comfortable fit, but I also have broader shoulders."
"the medium did not fit in length of sleeves or to my waist. Too small across my shoulders and lats. The weight of the material is nice and warm, but not made for full sized adults. I'm 5'8 and 120#, so not a large human. The mens medium fits great!"
