Boyfriend is now addicted to PrAna
I liked that PrAna gave us the choice between different flannel weights - there's nothing more disappointing than thinking you're going to get a nice heavy flannel and getting a light cotton plaid button-down instead.
I bought it for my boyfriend for Christmas, and he fell completely in love with it. He said it was the nicest flannel he's ever had, and now he is buying all of his clothes from PrAna. So we'll probably go broke thanks to this flannel

My favorite flannel
Good looking flannel w/the perfect weight lining. I prefer snap closures & prAna nails these snaps perfectly. Great fit for my 6’1”, 190 lb frame.

Excellent light jacket or layering piece.
Very warm and very soft, Nice to wear out but soft and comfy enough to lounge around the house in like a hoodie.

soft and warm.
This flannel shirt is very comfortable. The inner lining is soft on the skin. It is also very warm. It is so soft and warm, I seem to wear it almost everyday. My one minor dissatisfaction is that the fit is not as slim as I would like.

Warm!
It is a lot warmer than I expected. I love it. I'm 5'10" 170 lbs, I got a medium. It fits well, a bit tight in the shoulders but most Prana stuff is tight in my shoulders.

I'm returning it.
The Asylum shirt used to be one of my favorite shirts. I have two of them from 2016 and prior to that and they are wonderful. This years model is just like last years, which I bought and returned. For some reason they no longer adequately sew in the thermal lining. It is only stitched in in a couple spots around the arm and the inner sleeve is only stitched in in a spot or two. It used to be sewn the entire length of the arm thus the lining stayed in one place. That is no longer the case and the lining bunches up and moves when you put your arm in and to me it remains uncomfortable and lumpy. I learned my lesson. I will not buy anymore of these. And, by the way, I am a loyal, steady customer of Prana men's clothes. I hope this is not the signal of declining quality.

Heavy and Warm
This is surprisingly heavy and warm. It can almost work as a jacket by itself. Very highly recommended
