Its hard to say if this is my favorite piece of waterfowl gear from Sitka or not, but its definitely at the top of the list! While the outside may not be the most durable material ever, its designed to be an insulation piece,(so far I haven't had any issues with it holding up). I've paired this with the FV, the Hudson, & both the FV, & Hudson when it was 0 with a 40 MPH wind & I stayed nice & warm while all my buddies couldn't wait to get back to the truck. I like this more than the duck oven, it is less "poofy" & has insulation all over. If you are on the fence, get this jacket, you will not be disappointed!

Extremely comfortable. Extremely warm I wore if skiing in 30 degree weather. I’m 5’11 160 and the large tall is a great fit

Seems very well made but difficult to find a size that fits (possibly could be my body shape). I’m 6’4” 205 and the XL-tall is ok as far as length but too large in the body (more of an outer layer fit). So I tried a large-tall and I can’t imagine a regular large since the tall was close to belly button length-very short. It was also too tight in the chest. Not at all knocking the jacket-just wanted to stress trying the coats on before buying. Going to try the XL-tall Hudson next.)

This jacket is warm , lightweight and comfortable but tears easily. I have never worn the jacket hunting. It has never been in the woods. I have worn it maybe 3 times a week to walk for excercise, and have only had it less than 90 days. The jacket had 2 tears in the front by the zipper 2 weeks ago. I asked my wife to fix it because I did not realize that it could be repaired at Sitka’s expense. I just found another tear on the other side of the zipper. I have not worn this jacket anywhere to have caused this type of damage! I am very disappointed in this jacket and will not recommend this jacket to anyone. Way too much money for such poor quality!

This needs to be in Timber.

Now why this is the greatest thing since sliced bread. I tried the Duck Oven, Dakota, and the Fahrenheit. While the Duck Oven and Dakota can serve as a great insulation layer/jacket, they pale in comparison to the Fahrenheit.

Unlike the others, it fits like a glove from knuckles to shoulders and neck to waist (even to the armpits). I like that it keeps tight to the body to seal in warmth. The hand/thumb cuffs are so dialed in that they’re thick enough to keep me from not needing to wear gloves in sub-zero Minnesota temps while picking up the decoy spread but thin enough not to give the muffled sound that gloves inherently and unfortunately make when calling. They also slide perfectly under the water sealed cuffs of the Hudson and Boreal.

It’s light as a feather but bombproof. I’ve put mine through the wringer the past couple seasons: carrying logs over the shoulders to build and brush out blinds, the standard duck hunter’s daily shoulder weights of hauling countless, heavy decoy bags, blind bags, shotties, chairs, etc. at the same time, and going through the occasional briar patch for downed birds.

Seriously, don’t look anywhere else for an insulation layer. It’s the one jacket that I’d take if I could only have one jacket for the rest of my life. If it came in Timber, it can go to my grave with me or passed down as the family heirloom.

Jacket is very warm and comfortable. However, it is not durable at all and will rip and catch in the zippers. I have had the jacket for a year and it is being sent off for repairs. Two huge rips from minimal use in regular hunting scenarios. For price of jacket, it should be more durable.

Hi Kaleigh // Thanks for your review, we really appreciate the feedback. We are sorry to hear of the issues with your jacket, but are also glad to hear it is heading in for repair. That being said, the Fahrenheit Jacket is meant to be light and packable, not necessarily to be the most durable. It can certainly be used as an outer layer in some cases, but majority of the time the proper use is underneath another garment. If you are looking for something to wear routinely as an outer layer while still utilizing Windstopper, I recommend taking a look at our Dakota Hoody or Dakota Jacket. I hope this makes sense, and please don't hesitate to reach out with any further questions or concerns.

Great Jacket, Needs to be made in Timber too, like the vest. I am not a fan of body mapping insulation jackets. They leave too many cold areas. Like this type jacket much better.

Unbelievably warm, might be my best Sitka piece I own. Wear it as a underneath or as an outer layer and you will remain toasty! Just got back from a duck hunting trip and was stationary for hours in 20 degree 20-30 mph winds and this jacket kept me more than conformable. Just buy it!

Best jacket I have ever used! I bought the Cabelas Instinct Jacket thinking it would work great, but it doesn't fit well, its not very warm, and its hood is bad. The Fahrenheit Jacket is 10x lighter and 10x warmer than the Instinct. I recommend this jacket to anyone looking for a mid layer or outside shell.

The stuff dreams are made of. I bought the Fahrenheit vest and decided to get the jacket also. I'd been accustom to Patagonia jackets (have tons of those) doing double duty for fly fishing and hunting. But after wearing this jacket, you quickly realize how other brands just don't measure up. This jacket NOW does double duty. The down Patagonia jacket for fly fishing is great until it gets wet. And yes, other brands use Primaloft, but the cut and fit of this jacket is better than any for activity—the others are too loose or too fitted. The Gorewindstopper (not one of my Patagonia jackets uses it) works perfectly. I've worn this jacket on super windy days on the river and never got cold (in November). You really can't layer under this jacket, just add the heavy weight zip t (got one of those in Elevated II) and you're golden for anything the east coast in OCT/NOV throws at you. I wear it under the Delta Jacket and the system never lets me down. However, for DEC/JAN/FEB I use the Boreal jacket. You can't go wrong with this jacket.

Everything I was looking for in an insulation/ outerwear layer duck jacket. I got this jacket over the duck oven because my mid and lower back is what gets cold and I didn't like how the torso of the duck oven was not insulated. This jacket is fairly light weight and not very puffy at all while still providing an incredible amount of warmth from top to bottom. The wind stopper layer really adds to the versatility of this jacket making it an excellent outer shell when necessary. The thumb holes are useful when sliding a shell over top and other than that I don't use them, and they aren't in the way. The material is durable and hasn't picked or plucked even going through brush. Great jacket and for a lot of people I think this is the better choice over the duck oven.

Following the Call: Honoring a Waterfowl Tradition

My love of the history and tradition of the American duck call goes way back. I was eight years old when my parents handed me an old shoe box of calls that had once belonged to my grandfather and his brother. The calls fascinated me, and it wasn’t long before I started my own vintage collection and began attending duck calling competitions. Eventually, I was spending what would become invaluable time with Butch Richenback at his Rich-N-Tone Duck Call shop here in Stuttgart, Arkansas, learning everything he had to teach me.
