Kelvin Aerolite Jacket Reviews

I have not owned this

I have not owned this piece for long, I usually try and wait a couple seasons before writing a review. I have worn this on 4 hunts now and it has become a main piece for me now. It is very warm for how light and thin it is. I layer it over a grinder hoody and have a Fahrenheit vest over top of this. I was hunting in 30 degree weather with 17 mph north wind and was warm

AWESOME - I own 4

AWESOME - I own 4 different colors of this jacket and wear them according to the pursuit or heading into town. Being taller I enjot the tall sizing. I do recommend ordering up a size for additional layering and movement.

I'm a tall thin guy.

I'm a tall thin guy. It's nearly impossible to find jackets that are long enough without being gigantic. Enter the large tall size. I was so excited when I saw sitka makes LT sizes and I really need a camo puffy jacket. I tried it on and it was perfect until I put the hood on. They designed it with scrunchy elastic that is so tight you can't wear a hat underneath and can't have glasses because the hood is so tight it pulls them both down really hard. Bummer. Almost found a perfect jacket but not being able to use the hood makes it a no go. Sadly, returning.

I am 6' 2' and

I am 6' 2' and 235. Ordered an XL which didn't leave any room for anything other than a t-shirt. Ordered a XXL that leaves plenty of room for anything I want under it. The XL was a little snug in the shoulders. The XXL is not snug anywhere. I prefer the extra room. Nice jacket. Sale price sold me on the jacket. I own lots of sitka items. Usually not disappointed.

Just received my Kelvin AeroLite

Just received my Kelvin AeroLite jacket, quick shipping, great sale price. After looking over the jacket, I found no threads hanging, great quality as always with Sitka. This jacket folds up to nothing, and takes up basically no room in my backpack. As for sizing: I am 6'0' 180lbs, athletic build, and with all my Sitka apparel, I always buy size LARGE, this item fits perfectly. To go one step further, I tried on a core base layer, mid layer, and the Aerolite, no problem shouldering a long rifle. The only slight negative, is the hood is a little noisy. This makes no difference to me. Don't hesitate buy one on sale.

Light weight jacket. Decent warmth

Light weight jacket. Decent warmth using at about 34 deg with base layer. The problem is the hood. The material on the inside of the hood is terrible. It sounds like I'm wear a potato chip bag on my head. The material rubbing on my head is so loud, making it not usable. Even just sitting and glassing. It's just too loud and annoying with the slightest movement. I tried layering the hood with a beanie and merino hoodie. Still no help. I'll be returning for this reason.

This jacket is incredibly warm

This jacket is incredibly warm especially for the weight. I’m 6 foot 215lbs, I wear an XL in just about everything from Sitka and this jacket in XL fit great except for the midsection. I could probably fit a basketball under it. I would recommend trying to find a dealer to try on first if possible if you think you may be in between sizes.

By far the best quality

By far the best quality jacket in the market. No flaws and no weaknesses in this product or any SITKA product.

SIZE XL: I am 5'10'

SIZE XL: I am 5'10' 190lbs with a 46' chest, 35-37' arms, and 34' waist. The insulation and material seem excellent. But my goodness I can fit a watermelon under in the abdomen and cannot extend my arms or bring my elbows together. Not sure who these are cut for but it's not for those with wide shoulders and an average waist.

Purchased one of these in

Purchased one of these in thunder color at a lower cost but immediately threw it in the wash to see if they claimed is true.. It IS true.. it's warming me totally soaked... crazy warm when wet.

Love this jacket. 6’3” 190.

Love this jacket. 6’3” 190. Large Tall fits perfectly. I wore this during Colorado’s 2nd rifle season last year and found that it kept my temperature very well regulated. I never felt too hot or cold, when hiking or glassing and a good jacket for hanging out at camp in the evening. Not for busting brush or rain protection but a great insulation piece and does that very well.

I was skeptical on this

I was skeptical on this product. I love the Kelvin lite hoody. That said, this jacket is everything that jacket is but lighter and more refined. This piece will be in my pack all summer and fall. Even bought one in Black for around town.

Tried out a few different

Tried out a few different lightweight jackets that were packable as a piece of cold weather gear for backcountry elk hunting. This was by far the lightest and most packable in my bag and WARM! for the weight this thing is insanely warm, I end up wearing this thing for everyday use during the winter, I would say this is my second favorite piece of Sitka Gear and I own a lot (first being the boreal aerolite because of the brutal conditions it saves me from) a few things to note... it isn't very breathable so if your going to hike with this on expect to get sweaty and its a nylon type material so its not very quiet and going through thorns and stuff will tear it up. But if your looking for a very nice packable jacket for glassing or at camp in the AM/PM or even as a everyday piece of gear its worth it imo

Sitka’s rating of this jacket

Sitka’s rating of this jacket was a little modest. It’s BA! I’m a bigger guy and often times Sitka jackets are a little tight in the shoulders. This jacket fits perfect. It’s warm and keeps the wind off. It will be one of, if not your favorite piece.

Having bought the vest for

Having bought the vest for a few months I was very curious to see what a full hoodie would do. I am quite impressed. Not too bulky and fairly light but it does feel heavier/thicker than the vest. Wearing the hoodie and the shake dry jacket on top I feel very comfortable even with freezing temperatures. I think the GORE-TEX over it makes the big different but the hoodie on its own is warm enough and comfortable enough for every day use. I went with a size Large and it has excellent fit. I am about 45 chest, 34 waist and i have full movement with a base layer. The size is good enough to wear, say a fleece zipper and still feel comfortable, not too tight to have full mobility. Highly recommended!!!

I have to admit I

I have to admit I have been on a Sitka buying binge over the last year and a half since I purchased my first product. OUT OF EVERYTHING I HAVE PURCHASED SO FAR THIS IS MY FAVORITE.....and everything has been better than advertised on all products. (That's why I have two big totes full of Sitka gear at this point.) The whitetail hunting gear from bibs to hoodies to jackets was so good I wanted to buy some Sitka gear for 'everyday' use. I was stunned by how warm the Kelvin Aerolite Jacket keeps me while being so light. Large size fits me perfect. and I'm 5'7', 175 pounds. It actually feels like it is a heated jacket. 30-50 degrees and it's all I need. Above 40, I don't even keep it zipped up all the way. I get lots of compliments and questions about it when I wear my black colored one out and about. HIGHLY RECOMMEND IT!

I read the other reviews

I read the other reviews before buying this jacket. I was skeptical when they said how light and thin this jacket it. Then I looked into the aerolite insulation. It seemed like the real deal. That's why I made the purchase. I was able to test it out recently. I'm from Utah so this is without humidity. It was 30 degrees out and blowing 20 mph. I was only wearing one of those thicker Carhartt shirts underneath. It blocked out the wind easily and kept me warm! I had on jeans and some Cabela's midweight bottoms underneath and my legs were getting cold instantly. This jacket is the real deal.

As a guide and outfitter

As a guide and outfitter this jacket has been put to the test. Being out in Kansas where the wind can blow … this jacket cuts the wind very well. The added warmth of this jacket for the light weight is amazing! It needs to be worn under an outer jacket for archery due to the louder profile. Overall I highly recommend this layer to your layering system!

This jacket is hands down

This jacket is hands down my favorite Sitka piece. Stayed extremely warm in a very snowy Colorado elk hunt last fall. Own a large tall and the fit is perfect!! Stayed comfortable all week in 14-25 degree days. (NOTE: we don’t experience humidity like most of the country) But of all of the Sitka pieces I own, this is the most important. If you don’t purchase anything else at least buy this jacket.

I usually wait a year/season

I usually wait a year/season before writing a review but I have to say you don’t have to wait to buy an Aerolite. For being this lightweight it shouldn’t be this warm. It’s better than some of my other, more expensive puffy pieces. It’s a new favorite for sure.

The quality build of this

The quality build of this jacket is amazing. The attention to every detail and the high quality material is just far above anything else I have purchased over the last 40 or so years of buying hunting/fishing gear. So do yourself a favor. Spend the big bucks and you will not be disappointed.

I've worn this outside in

I've worn this outside in single digit windy weather this winter a lot. You just don't get cold in this thing. The wind has no effect either. And it is so light, you don't know you are wearing it. And you don't get over-heated in it either. I haven't touched any of the other coats I have since I put this on. Nothing like it!

Great jacket that is very

Great jacket that is very warm for how light it is. 10/10 recommend to wear every day!

This jacket is a great

This jacket is a great piece to wear by itself but its meant to layer you put any type of jacket under this and you will 100% stay warm.

Amazing jacket. Really impressed with

Amazing jacket. Really impressed with how warm it is. I even use it on duck hunts. Definitely going to invest more into the aerolite system.

This jacket is great so

This jacket is great so far. It's very lightweight and with just a t-shirt underneath pretty warm. Can easily wear as an outer jacket or as a layer. I bought a solid color to wear around town and under my ski jacket. I am 5'10' and 160 lbs and ordered the medium. It fits perfect. My only knock is that it is short in the front which is typical, in my experience, for Sitka jackets. I would prefer their jackets to sit a little further below the waist than they do. Overall though, I would order the jacket again and look forward to its use.

Great jacket. Amazing warmth to

Great jacket. Amazing warmth to weight ratio. Also looks great and fits well.

I have been really impressed

I have been really impressed with this jacket. It is the perfect warmth for archery elk season while glassing and very pack-able when not being worn. Fit is perfect for me.

Wore this on Saskatchewan hunt

Wore this on Saskatchewan hunt in temperatures of 2°F to 30°F in a pop up blind to test the layering. Seemed thin and I was skeptical of how warm it would be but I was pleasantly surprised. I layered with two heavyweight wool long johns, the Celsius Midi, Kelvin Aerolite Jacket, and Incinerator Bibs and I was not chilled during my nine hour sit. Would like a little more room in arms as us gun hunters don't need such a tight fit as the bow guys. Great job SITKA!

Awesome jacket. Absolutely my go-to

Awesome jacket. Absolutely my go-to piece from now on. It's an outer-layer when it’s cool and a mid-layer when it’s cold. Super compressible. Way warmer than it should be seeing as thin as it is. Relatively silent and not nearly as loud as the Kelvin Lite Jacket.Solid color can be worn anywhere. Warm when wet and I mean wet! Wish it came with a stuff sack and removable hood. Hood although is a good snug fit!

The jacket is very warm

The jacket is very warm and made well like all Sitka items, but it is far from the athletic fit that I have grown to expect from Sitka products. I have an athletic build, 185 lbs, 6'1, and this jacket looks like a poncho on me, tons of room around my chest and torso. I ordered my normal size of Large.

This jacket is extremely packable

This jacket is extremely packable and lightweight yet keeps me more warm than several other parka style jackets I own. Well worth the money and will be my primary mid-layer for the later hunting season and my outer layer during the early season. The lack of bulk makes this jacket extremely versatile without giving up warmth. Most impressive was how I stayed warm after getting caught out in a rain storm...incredible performance.

This was a go to

This was a go to piece of clothing on my northern BC Caribou hunt. Lightweight, packable and was kind of magic in that it kept me the perfect comfort level across a wide range of temperatures. I am 5'9' and 230lbs so on the hefty side and the XL was perfect for me. I am pretty broad chested so have hell of time to get jackets to fit my shoulders right. It does have a more forgiving fit in the arms compared to the Kelvin Lite jacket. I pretty much wear this jacket all the time now including around home.

I have the original Kelvin

I have the original Kelvin Jacket and the Kelvin Aerolite Jacket. Each has its merits. The Aerolite weighs less, better with wind and more packable. I have hunted wearing both jackets (at different times) in upper 20s and low 30s morning weather and I was warmer in the original Kelvin Jacket which I appreciated when I was static. Also, the original Kelvin Jacket allowed for better breathing and moisture wicking. Overall I prefer the original Kelvin Jacket. For me, a mid-layer, should be warm and moisture wicking. There are other layers for wind/water protection. Since the Aerolite does not breathe as well, I think Sitka thought they could reduce the amount of insulation to retain weight to warmth ratio. This is a great jacket for the minimalist, but I definitely prefer the original Kelvin Jacket.

LOVE this piece. I haven’t

LOVE this piece. I haven’t taken it hunting yet, but I live in Alaska and have worn it in a ton of different conditions so far this fall. From rain and cold to snowing in the 20's. Highs were in the 30's the other day and I wore with a medium weight hoodie for 3-4 hours outside. Did not get cold at all. It’s definitely NOT an active insulation piece though. Get moving too much and you’ll get toasty in a hurry. I am 6’4, 210lbs and I ordered a large initially for every day use. It fits amazing but is a little short and not much room for layering. I’ll keep that as my town jacket and just ordered a second in XLT for hunting. Looking forward to testing it in some harsh conditions 2 weeks from now on a PWS Blacktail deer hunt. I have the Kelvin Down Lite Hoody and the Kelvin Down WS Hoodie. It’s definitely not as warm as those…but the synthetic adds a lot of versatility.

Not only is this an

Not only is this an awesome piece, but it is what Sitka claims. This jacket is by far one of my favorite Sitka pieces. I hunt in mine and wear out as well. It runs true to size. I stood in the misting rain at 42 degrees for over an hour and never did I get wet or cold. GREAT JOB Sitka. I will definitely be buying another color. If you do not have this Jacket you better get one.

I bought this jacket for

I bought this jacket for it’s light weight and packability. I took it on a 5 day backcountry elk hunt and really enjoyed the versatility of the Kelvin Aerolite. I was surprised at how well it worked keeping me warm in a wide range of activity. From hiking, glassing after the sun went down, and even sleeping, the jacket was very comfy and functioned well. We got rained on from a storm that came out of nowhere, and it was still warm and comfortable to wear. It’s a great jacket!

This is the perfect puffy

This is the perfect puffy jacket. I'm blown away with the warmth to weight ratio. Sitka's attention to detail on this jacket shows. The stretch cuffs slide over my release and fit over a watch while still sealing out the wind. It is warmer than the Kelvin Active Jacket. I'm 5'11' and 185 lbs with a muscular build. I wear a size large in all Sitka tops, and this one fits perfectly with room to layer. I love it so much I got Subalpine and black. The only complaint is it's not silent, but still not loud. I don't think the noise will be an issue for archery elk hunting.

Just got back from 10

Just got back from 10 day elk hunt in Colorado. Temps ranged from 34°F to 44°F for lows and 54°F to 65°F for high. Found myself wearing this jacket just about all the time. So lite and comfortable. Warm with minimal layers. Definitely a great piece of clothing. Sitka did very well with this.

Just got this jacket and

Just got this jacket and without testing it out yet due to it being August all I can do is give a unboxing review. First thing you notice is it is extremely lite. I mean it. I have shirts that weigh more. Fit is perfect. 5'8', 195 lbs. 45 inch chest. Ordered a large. Im surprised at how quiet it is being kinda like a puffy. Its not fanatic line quiet but I will definitely wear whitetail hunting if needed. I ordered this for archery elk hunting and it will definitely fit into pack for that. I will try to do an update after my elk hunt this September. But if you're on the fence, I would recommend you pull the trigger.

I love everything about this

I love everything about this jacket except how noisy it is. I archery hunt and its a very loud jacket to move around in in the woods.

This is my first piece

This is my first piece of Sitka gear and wong be my last. For reference I am 6'3', 215 athletic build and I ordered the XL Tall. It fits me perfectly and the quality is awesome. I was worried when I took it out of the box because it feels pretty thin. But then I put it on and could instantly feel my arms and head getting warm. I have no doubt it will be perfect to throw on while glassing between hikes and keep me warm. The sleeves taper perfectly, have a stretch panel down near the cuff so it easily goes over your hands and wont interfere with my bowstring. The hood is also perfect as it isn't bulky, doesn't block your peripheral vision and works great with or without a hat on. The body is a good length and wont let in drafts while sitting to glass for animals. The Subalpine camo is amazing as well and will work pretty much anywhere. Overall, I am very impressed with this jacket. Will update after season on durability.

I like the jacket and

I like the jacket and overall quality seems great. I did have to size down. I typically wear a Large at 5’11, 186lbs, 42” chest but the Large seemed to swallow me. The medium will work the best for me in this specific jacket. Hopefully, that helps if you're trying to decide sizes. Standard fit make sense for it to fit for more layering.

Just got this today. The

Just got this today. The reason for 4 stars is because I haven't tried it in the field yet. But as soon as my archery elk hunt is complete I will give a updated review. So this is a first impression review on quality and fit. 4 stars being the highest. Fit is perfect. Im 5'9 190 pounds with a 45 inch chest. I ordered a large. Build quality is very good, typical sitka. Packs down very small, weight is mind blowing. I have marino base layers that weigh more. And im very surprised that this garment is very quiet for what it is. Nothing like a typical puffy. Not silent, but you could stalk wearing it. Hood fits very well. So without testing in the field yet , I can say this product has no buyers remorse attached to it.

Not too impressed with this

Not too impressed with this product I’ve been a long term Sitka fan for a while however this doesn’t live up to the name…. After one hunting trip there is already wear and insulation busting out of the seams. I also washed it according to manufactures spec hand washing it with a down specific detergent rinsing twice and then tumble drying with tennis balls and my jacket has water stains all over it.
