Celsius Midi Jacket

Why We Made This

Hunters need a lightweight packable layering solution for the oft-changing conditions of sitting on their stand. We developed the Celsius Midi to be extra versatile, warm and packable with PrimaLoft® Silver Active insulation. We tapered the sleeves for clean and easy draws while archery hunting and the smooth face makes layering super easy. The addition of the safety harness port permits donning and doffing while in the stand, and a DWR finish sheds light precipitation and prevents the face fabric from wetting-out.

This jacket packs great, it’s super warm, breaths well, and for a down jacket, it’s SUPER quiet and incredibly versatile. You can’t beat it for deer hunting on those cold days, especially paired up with the Fanatic or Stratus!

I can honestly say this is the single most versatile piece that I have from Sitka and it's also my favorite piece. I wear this jacket from the first day of the season until the last and on out from there. This jacket folds up super compact and it lives in my pack all season for all occasions. It is perfect for those early season mornings and evenings when the sun is behind the horizon and you need just that extra layer of warmth. I wear it as my walk in layer from mid-late season when I don't want to sweat walking in and then leave it on as an insulation layer. I even wear it as a light jacket getting to and from classes around campus in the winter time and its keeps me far warmer than some of the other heavier jackets I have do. Absolutely a vital piece in my whitetail and every day system

The ideal jacket for any whitetail hunter. Probably the most versatile jacket of ALL sitka clothing, and that's really saying something. With its incredible packability, efficient weight to warmth ratio, and superb comfort..look no further!!! Can be used as a mid layer under neath the fanatic or stratus system, and i sometimes even wear it under my jet stream jacket on windy days! I am 6'3 205 pounds and the XL fits great with plenty of room to layer but still has a nice athletic fit and isn't too baggy.

I bought this jacket to go under my stratus jacket. However this turkey season got very cold, mornings in the low 30s. That said this jacket is the only thing I wore and i stayed warm the whole time. My only grip is where my best rubbed the outer shell it has fine threads poking through the shell. It’s the primaloft I imagine. Overall I’m glad I bought it, very comfortable to wear.

You will think this jacket isn’t gonna be warm enough based off how thin and light it is. And you would be dead wrong. I’ve never worn a jacket this light and warm in my light. Not to mention the fit is perfect. I’m 5 10 185 and large is a perfect fit. I layers perfect with my baselayer and fanatic hoodie under it. Can’t say enough good things about this piece.

I wore this jacket over a light weight t-shirt along with my fanatic vest, it was 28 degrees and light snow, wow was I impressed. Later in the season I hunted a very cold windy day here in the north east, 11 degrees, had my Sitka base layers, equinox pants and this jacket on for the walk in. When I got to my stand I topped it off with my fanatic bibs and jacket, stayed toasty warm even with that biting wind. Topped it off with the fanatic hat, these products are very well made and worth every penny in my opinion.

This jacket is definitely as Sitka says, a "puffy" jacket. That being said, I do really like this jacket and I think it would be most hunter's best friend in October through early to mid November. My ideal temperature range for this jacket is 65-40 degrees and down into the 30's with either no wind, or with the stratus vest or jet stream vest when it's windy in the 30's. It is the perfect jacket for the mid season as a whitetail hunter but is not meant for the late season, unless it is used as a mid layer piece under the Stratus Jacket or Fanatic Jacket. I was originally going to buy the Celsius Midi jacket but I figured it would be warmer than this one and I wanted a jacket I could wear in warmer temperatures so I went with the Celsius Jacket instead. My only knock on this jacket is where the insulation is cut out on the sides. I'm not really sure why the insulation isn't there but it's not really that big of an issue. Still a 5 star product with my minor knock on it.

Just for reference, I'm 6 foot and a bigger guy and I normally wear an XL in clothing but ordered this in XXL. I did this because I wanted to have some room to wear a vest or layer under this if I wanted to wear it in the 30's, and I've definitely got that room and am still comfortable in it without layering. I imagine I could have ordered this in an XL and got by just fine but ordering a size bigger is just going to personally help me wear it in a little colder temperatures.

I hunted one of the coldest days of the year so far here in Northern Michigan, unfortunately without my Fanatic Jacket (insanely warm). All I had was a baselayer and the Celsius Midi, with my Fanatic Bibs in 15* with 10-15mph winds and snow.

I was certainly cold by the end of the 4-hour sit, but not frozen solid due to the unbelievable warmth-weight ratio of the Midi. I would never guess a jacket this thin would be so warm.

In normal circumstances, it acts as a very solid layering piece to add to a lightweight outer or a heavy weight outer. Huge fan of the jacket.

I wear a Large in most everything Sitka, and this jacket is no exception.

Great layering piece or outer when approaching the stand! I layer this under the Stratus Jacket/Bib and I'm good down to low-30's. Cut is good to fit under the bibs, and packs down in a backpack well!

Excellent jacket. When I first purchased the product I was expecting to use it as a base layer due to the thin design, but was very impressed. Just recently hunted in the polar vortex we have been experiencing in the states. I was hunting in single digit temps with only this jacket and a base layer underneath. Kept warm the whole day didn't get cold once! Super Super warm and quite!!

This jacket may be the most versatile piece I have. It’s lightweight, packable, and very warm! I purchased this piece with intentions of wearing it as an outer layer in the 50s and 40s and then adding the Stratus jacket over top when things get windy or colder. I tested it out today (30s and snowing) with only a midweight layer and 145 merino underneath and stayed very comfortable but I believe it will shine as an insulating later (which is what it’s designed for) on days like today and colder. The fabric is very quiet and this thing is just awesome to wear. Think of it as a puffy without the noisy outer shell and less bulk. I’m 5’9,175, and the medium fits perfect. For reference, I am a size large in the Stratus but the fit is very similar. I chose large for the Stratus to have a little more room for layering underneath. If you already have the Stratus and need a little more warmth or just want a super comfortable piece that’s very versatile to add to your closet, look no further than the Celsius Midi.

This was a great add to my system. I pack it now for every hunt it seems minus early early season. I have a medium and almost wish I had a large but it fits nice, I just would probably but it on as outer more in cold weather with larger size when wearing bibbs. I’m 5’10” 178lb and the medium fits great just with the bibbs I have to put it inside Bibb not to feel like it’s stretched skin tight. With that said they didn’t design it to be an outer so it’s perfect for what it’s designed for. Mild/low wind weather I wear it with a fanatic hoody it’s money, normally throw it on after I get settled and that warm feeling from walking in and climbing has gone way. Cool to cold with wind it’s under my stratus jacket, rain under my rain gear. Like I said do all layer piece for me. I will beg and second the motion to please make a set of midi pants as a under layer for the stratus and fanatic bibbs. Just stick a warning label not designed for brush and briar walk ins to offset a warranty claim. I’d wear then in on non brush/briar walks and layer at tree for cold all day sits, or all day rain sits in cooler/cold weather. I wear a base layer and equinox pant now, these pants would probably cut one layer of waist bulk and just be good with merino underwear. So my 2 cents buy the jacket, and beg gore for a pant set to match!

This is my favorite piece of Sitka clothing I own. I hunt whitetails in Iowa and this coat is versatile enough to be worn as an outer garment during cool early season hunts and a layering piece during the cold late season hunts. This coat always goes with me to me tree stand... period. It is extremely quiet, warm for its weight, and I love the thumb holes in the sleeves for when I wear it under my Fanatic coat. If you're into Sitka gear and hunt whitetails in the Midwest, this is a "must have". Two thumbs way up!

I wore this jacket as an insulating later underneath my fanatic vest this year whitetail hunting. After hours in a treestand in very cold Wyoming weather this jacket performed flawlessly!! Very quiet with just the right amount of insulation. I really like the form fitting sleeves and the thumb hole cuffs are awesome!! Great as a layer or by itself. I found it very similar to my favorite Subalpine active jacket. Fit was true to size. Can’t say enough good things about this jacket along with all my Sitka Gear!! Never disappointed!! Thanks guys!!

After wearing and using Sitka gear extensively for the past 5 years this new piece has to be my favorite. It’s dead silent, light weight, very warm and packs down to nothing in my pack. I’ve taken this jacket on every hunt I’ve been on this year. On mild days I wear it as a outer layer over my core lightweight and heavyweight hoody. Then on colder days I layer it under my fanatic set. The amount of extra warmth it brings you on those extremely cold days is just what I needed! The only downfall is the face fabric is not very durable but it’s not designed as a brush busting piece. Now if they will only make these in a pant for under the fanatic bibs I will be extremely happy!

Awesome jacket, definitely my favorite piece in my system. I use it as a mid-layer or while walking in to my stand. Using it stand alone, under my stratus, or under my fanatic I have been comfortable in my stand from 60 degrees down to 20 degrees with wind so far this season.

Very warm for its weight. Does well with light precipitation. Fits true to size, I'm 6'3'' 190 lbs and a large is perfect. Main issue is the sleeves from elbow down are extremely tight and narrow so they ride up when you wear it under a shell, and this also makes it very hard to wear more than 1 layer underneath. I have worn this jacket under the Goretex rain shell and it is a pain to get the sleeves to fit right. The narrow sleeve ends also mean you have to have an over glove otherwise with normal glove you will likely have a bare skin gap at your wrist. Neck is not as tall as it should be, or it should be adjustable with a pull string which it is not so you need a gator in the wind.

Fantastic addition to the Whitetail line up! This jacket is comfortable and impossibly light, especially when you realize how warm it actually keeps you, it's just amazing! The tapered sleeves are excellent for being able to easily slide your hands into the front pockets, which feels like they have hand warmers built in! I also really love the fact that you can snug up the bottom of this jacket without ever having to take your hands out of the pockets, the adjustment cords are built inside them, which to me is ingenious, and means less movement and no more dangly adjustment straps hanging around my waist! The chest pocket provides plenty of room for my range finder and release. Which the added harness pass through, this will now be my go to outer layer for most, if not all, the rest the season!

The Celsius Midi is obviously a new piece for this year so I plan on submitting a follow up review after the season. First impressions of the jacket though are incredible and I'm blown away by the functional movement married with the insulating properties of this lightweight piece. A perfect brother to the Kelvin Active for the tree-stand hunter with the addition of longer sleeves which mitigates the bunching up of gloves when the cuff meets the sleeve. Compressed sleeves for a clean draw cycle and easy layering might make this piece a new favorite of mine when October rolls around.
