Asylum Heavyweight Flannel

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

Great quality, beautiful flannel/ thermal

I got this as a present for my partner and he loved it so much we sent the other item I got him back to get another color of this one.

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.

So comfortable and a great fit it makes me want to buy another pair

Very warm and very soft, Nice to wear out but soft and comfy enough to lounge around the house in like a hoodie.

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.

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.

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.

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

This Flannel is made well, cozy and fits just as expected. Will definitely be buying more colorways.

This heavy-weight flannel is the perfect fit on my 6'2" 210lb frame (size large). can be worn on cool days outside down to around 50, otherwise a cozy indoor option.

Great fit and style. Super warm and solid material.

Love the fit, just roomy enough to wear layers but not overwhelming by itself.

Has room to be mobile and active, but no too baggy...perfect fit!

Lots that I love about this shirt/jacket - the color, the waffle lining, the snaps and the the quality of the flannel. I bought it one size up to be able to layer over shirts and wear as a jacket. Love it!

My husband absolutely loves this shirt! It is soft, heavy, warm and well constructed. The colors are beautiful. I enjoy seeing this hip shirt on my hubs. The fit is perfection. Two thumbs up!!

Warm, durable and versatile, this flannel performs well as a first layer or stand alone light jacket. I take it climbing and hiking all the time, as well as around town. Great product.

I love most of my prana gear, and as a small, athletically built man most of their clothes size small fit me nicely.

I bought this shirt because I love the colors, and my closet could use another heavyweight flannel. This shirt has a great weight to it, and makes for a nice warm layer.

Unfortunately, the cut is a little wide and boxy. In addition, after the first wash the fabric is pilling. I am hoping that this is normal, and doesn’t lead to serious deterioration.

I considered sending this one back, but overall like it and it’s place in my closet too much to let it go.

The Asylum flannel is very warm. With a water and windproof layer it prepares its wearer for just about the worst weather North Carolina can throw at it. It also feels great. I ordered a size up from what I usually wear and I’m glad I did. A couple notes: (1) it is less a heavy flannel and more of a light flannel with a waffle-knit shirt stitched to the inside and (2) I ordered the safari color and the gray seems to dominate more than it seems on the picture. It is still fairly vibrant, though, and I love the color scheme.

Amazing layer. I wear it a ton and love that it looks sharp for many occasions.

Great shirt. Really soft, nice lining. Makes a great substitute for a light jacket. My only caveat- so hard to find xxl in your stores and sometimes online. Please ship more large sizes!

Perfect over shirt for winter. Wear it all the time. Very square shoulders which is a little unusual.

I love this shirt -- it makes you feel bullet proof against the cold. I also really dig the pattern! The liner is a little awkward and makes the shirt always wrinkly, but I'm not wearing it to board meetings or anything fancy.

I bought the XXL for my husband. The shoulders sit a little low. I think it makes it look a little big on him, but the XL may be too snug. Overall a good shirt to wear over a T-shirt for those slightly cold days. Looks surprisingly good on too!

Can't stop wearing this flannel. The organic cotton is very soft and extremely comfortable. I work in the mountains and it keeps me warm while I'm moving around and great with one more layer on top. Too bad it isn't merino wool, or I'd wear it days straight. Ohh wait, I have...

Really great shirt, really a shirt jacket and perfect for cool days or for very cold days under a coat.

I got the black one for my husband and love it on him. It's sexy. It's casual. The colors are rich and vibrant but subtle (how is that?). The fit is good with long enough sleeves for a tall XXL man. It's also very warm and can serve as a sweater weight warmth. He was not certain about the colors at first but he hasn't taken it off for last 2 days. Hope it washes and dries well.

My dad loves these shirts. Bought him this for Christmas and he is enjoying it immensely.

This flannel, was heavier than I though as it has an internal layer which add an extra protective layer for cold and wind. It keeps me warm, and allows me take off my jacket when walking around in downtown Denver or Boise. Great Flannel and I recommend!

Fits as expected. Love it i’m ordering another.

Really like the Asylum Heavyweight shirt, wear it every day. Fits well and is warm for cool autumn/early winter evenings around the campfire

I really wanted to love this shirt but it wasn't for me. My issue was with the lining...not as soft as I would like and it bunched-up/folded over itself inside the sleeves. I wish it was more sewn in to the sleeves. Instead it felt like a loose fitting old-school thermal shirt underneath a flannel shirt. I suppose I would prefer a fleece lining better. It really isn't a bad shirt, just not to my liking.

The Asylum shirt is the perfect step up from a lighter weight flannel to something that provides a bit more warmth but also keeps style in mind. I love it and even bought one for my best friend for Christmas after he remarked how much he liked it. His wife already has plans to steal it to wear with tights as seems to be the popular style.

One minor issue is that the liner does not attach to the shirt everywhere and moves around a bit. Really a minor issue and maybe something that could be fixed in the next generation of shirt.

Thank you Prana for another great product.

I love this flannel. Beautiful design, great heft and works as a stand-alone or as a jacket over a low profile t-shirt. Best color schemes and pattern of any Prana flannels I've seen in the past ten years. I bought it in all three colors, and they've become my winter go-tos.

The fit was like a glove, form fitting with some room to be very mobile. The lining is super soft. I can wear a t shirt underneath or nothing at all. I ave received a lot of compliments asking "what brand is that" simply because how it fits. The color chosen was pretty cool. I will be adding a second asylum to my closet:)

Love it, it’s like wearing a waffle sweater and flannel shirt all in one

I ordered a small and it fits perfectly. I’m 5’6 150. It’s so cozy and warm. I love it. I ordered the orange color and have gotten a ton of compliments already. The thermal lining is great and has kept me very warm in the Chicago winters.

Perfect winter shirt or jacket. Very warm and goes great with black jeans!
I would order a size up as the lining is bulky, but very warm!

My boyfriend loves how warm and comfy this flannel is.

Best flannel ever! Bought my first one a couple years ago and just bought another. Perfect!

XL was too tight, be skinny and young for this. Quality and construction were good, seemed like before I returned it

Very well made and looks true to size. I look forward to giving it as a holiday gift.

This shirt is quickly becoming one of my go to shirts for winter. It's a very heavy lined shirt and I love how it feels! The only reason for 4 star is I like my shirts a bit longer.

This shirt is perfect. fits just right blocks the cold winds in the midwest, while not getting to warm inside.

Great quality, perfect weight. This is the only flannel you'll ever need, although I bought two because, well, why not. Great as a outer layer in 30+ degree weather or a base in colder weather. Highly recommended.

Perfect for cool crisp fall mornings or evenings on the town!

I was super excited to get this. Having a flannel that is a little warmer than my normal ones is the best. I have been so happy with how warm it keeps me and the color is amazing! The orange one fits fall time like a glove and I have gotten compliments from random strangers. The perfect cozy flannel for those sit by the fire kinda nights.

Prana Asylum Heavy weight flannel review
General notes from Use:
I have had this shirt for a few days in weather ranging from 40-60 degrees F. It has been fantastic. I would wear this with an undershirt and that is all I needed in this weather. Even in some wind and light rain. It is not going to keep you dry for long but it will keep you warm.

Outer Material:
Is warm and soft to the touch. It has great coloring and feels durable. I cannot speak yet to its durability performance as I have only had it for a few days not. Most importantly for what I was looking for with this shirt is that despite being soft and feeling good it still has a good amount of weight to it.

Inner Material:
The Inner thermal brings more weight to the shirt making it feel very warm and cozy. It makes you want to sit next to a fire with a hot drink on a frigid day. The only downside to the thermal interior fabric is that it isn’t very soft to the touch, but that isn’t a huge deal considering that I often wear a t-shirt under it anyway. I might suggest experimenting with other materials in the future to try and get that soft wart touch. Maybe try fleece.

Stitching:
Stitching is done very well on this product. I must be nitpicky to find anything wrong here. At the bottom corner of the shirt where several stitch lines end the tie offs are a little bit messy. My suggestion is to take a lighter to the ends of the strings that hang off. If done correctly this will get rid of loose ends and the stitching will remain ties down.

Buttons:
The buttons used are super snappy and feel firm. They don’t feel impossible to snap on and off, but they also don’t feel like the shirt is going to open in a stiff breeze either.

Sizing/style and fit:
The sizing is right on par with what I usually get with other brands, so I don’t imagine that other customers will have much of a problem with the sizing. The style is fantastic. I love the look and the colors. I only have one complaint about this shirt. I love to roll my sleeves 2-3 times on a flannel. Due to the thermal lining on this shirt that just is not practical. It is possible to do but it looks messy. I am not sure the best way to fix this problem however my initial thought is to make a stiffer, stronger cuff. Then the cuff will keep form when folded under the weight of the thermal liner.

I am really impressed with this flannel. I was very comfortable at freezing temperatures with just a t-shirt underneath.
