The BEST heavyweight flannel!
"I have two of these for myself (I like the men's version better than the women's for how I wear it - as a jacket), and I just about live in them during the fall and spring. I bought one for my husband. It fits him well; he has an athletic build, 5'10", 175#, and the large is a good size for him. He can wear a shirt underneath, but it still looks trim. He really likes the weight of the material. I also bought one for my brother as a birthday gift, but he hasn't received it yet, so I can't comment on how much he likes it. I love this flannel."
Great flannel, just not quite as warm as I had hoped
"Was thinking about this for a while with how pricey it is, but bought on sale and really like it. I will say it is not quite as warm wearing it on cold mornings as I expected, but it's just fine and looks great."
Just perfect
"So tired of hoodies and this shirt really replaces them 100%. Warm so you don’t have to keep the heat but stylish to wear on the town. Would love an option to have snaps as opposed to buttons."
I Feel Like A Real Lumberjack
"This is the best flannel (and the most dense!) that I have ever owned. I feel like I am wearing a weighted blanket when I am wearing it. Maybe it's just the lumberjack gods giving me a hug. I am not a lumberjack but I think I could fit in with real ones if I wore it around them. Totally rad!"
Best Forever Purchase
"Grabbed one of these for myself… being a husband and Dad of two girls I had to buy “boyfriend” sizes of the shirt to give to every woman in my house. We all love them. Heavy, durable, solid."
Fits small
"I bought this with the hope it would be big enough to fit over a few layers, but it's better on its own over just a small layer like a T-shirt. Warm, thick and nice quality overall."
Nice heavy flannel!
"This is what a flannel should be! Thick and warm! I'm a little lanky and I appreciate the longer arms. Very comfy!"
Super Warm and Soft
"Warm like a jacket but feels like a shirt. Feels heavy and sturdy but nice a soft when it’s on."
