Elevated Forest pattern Kelvin Jacket size XL. Plus ++++ Very warm and light. Good snug fit when zipped up around neck. Many compliments received on good looks. Minus - very static prone in dry Michigan winter. More than any other of my jackets by far. A little short in length. I am 6'1" and 220 lbs. An XL Tall size would be nice.

The jacket is extremely warm for its weigh, but not very durable in the field. The fabric has torn several times on the sleeves by thorns or brush. I expected it to be more durable fabric considering the cost of the jacket.

This is a workhorse of a jacket. Works great above or below a shell. Just spent 8 days in -15d C (5d F) in windy snowy northern bc moose hunting with bow. I wore merino base layer with a little vest and the Kelvin jacket. I'd throw my stormfront on top when quadding to my hunting area. I stayed nice and toasty the whole trip. When I was hiking I'd stuff it in my backpack. This is a piece of mind jacket. I never worry about the weather. I can get it wet or dirty and it still functions great. Nice lined pockets for warmth on your hands. I do wish there was a detachable hood for extreme cold. I have a mountaineering and ice climbing background so I know the limitations of down and I get a sick pleasure at pushing gear to its limit and beyond. That way I know the limits of what I can get myself into and out of. Great gear Sitka. Keep up the good work. And your customer service is top notch. They've completely taken care of any of my issues I've ever had. Thanks!

One kick butt jacket, wear it under a GORE shell steelheading in northern Michigan. Great warmth light weight and sweet looking. Handles 20 degree temps without a problem. Sitka is now my go to steelhead wear. Bad to the bone!

I have had this jacket for about a year before writing this review. Besides hunting I have a decent amount of experience in mountaineering, hiking and camping. With that being said Sitka’s Kelvin jacket along with all of their other products I own has bridged the gap between technical mountaineering, high performance outdoor clothing and injected it into hunting. I never leave home without a puff jacket at least in my day bag or truck and always had to turn to other places (non hunting company’s) for that option to use for my hunting load out. When I found the Kelvin jacket and started to use it I was extremely impressed with its weight to warmth ratio, quality and just overall performance. I have used it in the dead of winter in a tree stand with temperatures ranging from 0 to mid-30s with just a wool long sleave and Sitka’s traverse pullover on and never once was cold. It did a great job at cutting out the wind even though its not “rated for wind shear”. The only kind of negative I will say is that it’s not the most packable puff I have ever had but it is most certainly doable and not something I would hold against it in any way. If you are looking for a great piece of gear to add to your hunting kit I would defiantly consider this one.

A must have insulation piece and a key to staying warm in the freezing cold late whitetail season! Very impressed on how warm this jacket is, but incredibly packable. I will be purchasing the Kelvin pants very soon!

Very excited about the kelvin jacket. You can feel the warmth being trapped by the insulation and creating a heat pocket around your body. Plan to wear as an insulation and outwear piece. I like it so much that I plan to buy a solid version for wearing around town. Would love to see this in the forest pattern for the lite version. Would love to see a Kelvin beanie as well.

One of my most trusted tools for the high country. A friend turned me onto the Kelvin Jacket, explaining the warmth and comfort. After using this jacket by itself and layering it, I see what he means. This jacket cuts wind out and keeps a skinny guy, like me, warm!

Great jacket. Does it's job and more. Used this jacket under me shell last duck season. Always kept me warm. Even in 10 degree weather on Tillamook bay here in Oregon. And for me one of the best parts is my girlfriend likes the pattern. So I get to wear it alot more around town. Always get comments and compliments from people on it. Ive had it almost one year now and it still looks like the day I bought it. And I wore it probably between 60-70 this last year. GREAT GEAR

As a member of Special Operations in the United States military, I have worn just about every jacket under the sun. I purchased this set of top and bottoms before one of my more recent deployments and they performed far greater than I expected. I have worn them in about every cold environment imaginable and they have stood the test without compromise. One such trip took me above the arctic circle near the ocean...nothing is more miserable than the freezing and the wet in combination. Once again Sitka developed a product that surpasses all others. This jacket in unbelievably warm for a synthetic honestly blew me away! Bravo've done it again!

Pretty good jacket. Almost perfect all around jacket, except for the fact that it isn't completely waterproof. I take this on all my Alaska hunting trips.
