It is a thicker flannel material, comfortable, and durable. With some base layers it does great in colder weather without any extra bulk.

I’m 6’ and 205 and wear a standard Large in most shirts and all Sitka clothes I have purchased. This shirt fits great in the chest but is short in the arms and tail. Like all Sitka gear top quality material and warm but doesn’t give the flexibility if your working on the field or farm.

Shirt fits great and is warm. Felt like micro fiber at first feel but after a wash it was as comfortable as soft as can be. Doubt it could go tucked in but it wears great as a untucked shirt.

Sitka did it again, this shirt is great for everyday or in the field. The fit, the comfort, and the durability is spot on. I have it in three of the colors.

Absolutely love this shirt. Fantastic for cooler weather and around the house!

First disappointment from sitka, I typically wear a Large and this button up does not fit like the hunting apparel. At 6 feet tall the shirt fits short in length and ik the arms, I definitely would purchase this again in XL to see if it will fit better. Please come out with a tall series because this piece is solid in all the other ways a button up should be.

Nice shirt.. but for us taller guys its just not long enough and I'm only 6'1.

You guys missed the mark on this one. Fabric is nice, rubber buttons are not. They are unnecessarily difficult. In order to have the sleeves and shoulders fit comfortably, it is necessary to go up a size causing the body of this garment to be baggy. Shirt needs a redesign.

Very short. If you’re 6’ and wear a large normally this shirt will be much shorter than your other average button downs.

The shirt is amazing except for length in body and arms. If they made a LONG version of this shirt it would be perfect. Great construction and style. If you are over 6' SITKA will run short on you. Especially if you are tall/slim and need a medium etc. A lot of people I talk to love their products but can't wear due to length.

Extremely well made shirt that is quality exemplified in my opinion. This is a thick shirt that can serve as work attire or an outdoor event that is below 60°F. As for the fit I am 5ft 11in and 224 lbs and consider myself more muscular than average and the XL is spot on for me. I could easily get a t-shirt under it if needed. In comparison to other Sitka gear - I have XXL Jetstream jacket, 38R Mountain pant, XL vest. For Sitka base layers I am exactly in between the XL and XXL so I keep both in some instances. Hope this helps everyone. Again, this is a thick shirt.

I'm afraid to wash it to be honest. I tried it on and usually I wear a large in other flannels. When I wash them, they shrink in the arms so I ordered an XL. This flannel seems a little short in the arms. Other than that, it feels great, warm and durable. Only giving four stars, if there were tall sizes it'd be a 5 star review.

These are the most comfortable flannels I’ve ever worn! Warm and cozy feel, but still feels thick and durable enough to handle and work day you could throw at it. Sizing is spot on as well. These are a huge improvement over the original flannels.

The quality of this shirt is amazing. It is well constructed and very comfortable. The sizing is pretty true but it does fit a bit slim. I am 6’ 185 and wear a large.

Sizing is off from other Sitka gear pieces I own. I wear 2xl in all other pieces and could not button this shirt. Quality feels great, sizing is off.
