This is my favourite winter shirt from Fjallraven. It's really warm, and looks pretty fantastic. For sizing, I'm 6'4" and wear a 46" chest jacket. I ordered an XL in the Singi Heavy and it fit perfectly. There are some comments about the shirt shrinking after a wash...and this is true-ish. I've washed mine several times, and they seem to come out of the wash (cold wash, air dry only) much the same way a pair of jeans will. You can wear the shirt and it'll loosen and stretch back out to where it was before the wash.

I am 5'9". I ordered AUTUMN LEAF-DARK NAVY Size S but it is way too long (2 inches too long on my sleeves). They ran out of XS for the color. Otherwise, I love this flannel shirt.

Purchased a few weeks ago. I love the fit. I have a hard time finding flannels with a good fit. The olive green looks a little more grey in real life than in photos, but I'm happy with it overall.

Favorite flannel for sure. It's very thick material and the extra fabric backing on the collar and pockets makes it feel very sturdy. There are straps inside the sleeves which allow you to roll them up and then cinch them which is unique. Although I typically wear them down because the fit in the chest is excellent in that it doesn't restrict arm movements. Recommend checking out Fjällräven's measurements for shirting. I find them to be pretty accurate and consistent.

I usually don't take the time, or care to write down reviews. I got the orange-autumn coloured one last year and it's SO great. I can't wait for colder days so I can wear this again all the time. Very comfortable, nice and warm.

I've worn this shirt a few times so far and like it more each time. Feels durable but comfortable. They really paid attention to the details. Fits the way I expected it to. I will get more.

I actually really like the material (thick soft cotton), but the shirt doesn't fit. Ordered a Large (like my other Fjallraven shirts) and this one sits right at the top of my belt, I'm 5'10" and 210. It shrunk after washing, seemed to fit before. I'll gift it to someone a little smaller than me.

I bought this shirt for my husband and he absolutely loves it. It’s well worth the higher price; great quality and warmth, and the fit is perfect.

Very high quality flannel shirt. Looks sharp, fits well, heavy and good for the winter. I own flannels from a few different brands including another Fjallraven, and this one is already my favorite.

To me the shirt is overpriced, being just a typical slim fit cotton flannel. Nothing special about the fabric, nothing special about the fit or range of motion (e.g. no arm gussets). The sizing is a bit smaller than Fjallraven jackets (I own four in size M and L).

I love this flannel! It fits just right and looks great. Fjallraven has done it again. Good color options and I adore the little Swedish flag in the seam.

The friend I bought this for loves it and wears it all the time. It is a well-made garment. The colors are vibrant. He looks great in it. Thumbs up.

Christmas gift for my son, he loves it! He has long arms and the length was good for him. Have not washed yet, can’t report more at this time.

I picked up the red check Fjallraven singi heavy flannel shirt for a trip to Utah in late November. It arrived very quickly and was perfect for my needs. Temperatures during the day climbed to 50, and I found I didn't need a jacket at all wearing this.

I bought this flannel a few weeks ago and would wear it every day if I could. Best flannel I’ve ever owned. Fits great for a casual day at work. Also the perfect fit for a hike or adventure.
