Parka came in promptly and was exactly what I thought it would be.  I was updated regularly via EMail as to the status of my order and am very satisfied with the product and the service.

Snug fit for an XL/T. Fur trim will zip off but the hood is sewn in place and not removable. Heavy parka, but warm and sleeves close well with velcro fasteners. Price fair for what you get and 650 down fill is what makes it "superior". Two way zipper looks strong and it's waterproof. Why pay double to get a patch on the sleeve?

Am pretty happy with this jacket. Keeps you dry and I ordered it big as it is an overcoat for traveling. The only issue I had was that one zipper for a pocket did not have a smooth operation. The price made it a no-brainer to just keep the jacket and deal with it.  Would definitely order it again and it was the exact color as indicated.

Awesome jacket. Heavy, well made and durable.  I have a 46" chest and the XL size fits perfectly without the liner.  The liner is really snug, so if you're planning on wearing it somewhere very cold most of the time, then you should probably order your regular size and disregard the recommendation to order a size down.  But if that's the case, you're better off just getting a parka.  The sleeves are long, but they're easily rolled up and secured with the velcro on the cuff.  Finally, keep in mind that these ship from the UK and they have to go through customs.  My first order actually got lost in customs, but Sarah from the Transatlantic trading company took care of it and sent a replacement out in no time and at no extra cost.

I was given a Navy G-1 Flight jacket after receiving my Aircrew Wings in 1968. I was then a size 44R. Needless to say I have expanded my wisdom and girth. I gave this relic,(in excellent shape) to my son. I received Landing Leathers Flight jacket in Dec 2010. It is an excellent purchase. Warm, comfortable I would recommend this to my fellow Naval Aviation shipmates. Russ Rhinehart USN ret ATCS.

This jacket (this is not a parka) was purchased to replace a cheap hunting jacket I outgrew.  While it will only be used for a brief period once a year, it is a critical piece of gear especially when the temperature dips to 15F or less.

Look/Fit
The color is spot on.  Very bright blaze orange, though it has not yet been through the wash.  I was able to avoid getting blood on it this year, but I don't count on it remaining that way(will update).  It seems to fit well, I purchased an XL which was able to fit over a hoodie and bibs.  I generally wear Large to XL, and am 5'11" at 225lbs.  If you're much bigger than me, you should probably skip this jacket.  The inner layer is a drab green zippered sweater type thing, and could be worn on it's own in mild temperatures, though there is no hood.  It attaches via elastic bands in the sleeves, and one on the collar.  The sleeves take a little maneuvering to line up perfectly when wearing layers underneath.

Design/Function
Firstly, the outer fabric is very quiet.  I don't recall ever feeling so stealthy wearing so much gear.  The zipper was fairly quiet, though as a different reveiewer stated, the zipper is quite small, and plastic...I am very leary of plastic zippers though it seems the norm for modern clothing.  So far, the zipper hasn't given me any issues but is a bit difficult to get started.  The buttons on the other hand could be better.  Some of them snap well, some come apart very easily.  I did not use the hood, as I had a face-mask and hat and sweatshirt hood, but will test it out the next time I use it.  Also, the waist does not ride up like my previous coat, which was my biggest gripe.  The sleeves have two buttons, the tightest one worked very well to fasten around my glove to keep the heat in, though I'd rather have an adjustable elastic system for ease of use with gloves.  There are no inner pockets, which is a big bummer, but there are nice zippered pockets on each breast, as well as buttoned pockets lower down.

Performance
This coat was very warm.  I did use both layers, and as I mentioned before I had other layers underneath.  It was anywhere from 30 down to 20F, and I was very comfortable in the torso region.

I will update as the coat is used more.

Good jacket.  Still have it after 3 years.  A little puffy.  Just started to use it for hiking in the cold.  Somewhat stylish. Warm.  Covers your wrists and neck very well and comfortable!

I have continued to wear an old ragged parka because I have not been able to find a replacement at a reasonable price till now. This jacket packs a lot into one reasonably priced package:
  * Pit zips
  * Besides handwarmer pockets, another exterior zipped pocket for quick access to money or key
  * Storm flap over main zipper (I wish the pocket zippers were covered but they are not)
  * Snow skirt and a zipper to attach pants
  * Great insulation including sleeves
I will address some issues I read about in reviews here and on other sites:

Yes it runs small. I normally buy size medium jackets and they allow me lots of room for layering. Not this one, but it is so warm I won't need layers. I am  5' 2" and weigh 118, hourglass figure, and this jacket is snug and is about mid-palm length. From the back neck seam to the hem in size M is 26 inches. The jacket itself has a distinct hourglass shape.

Yes all those snaps on the front flap are a nuisance, but to slip in and out of it quickly, you can get by with just snapping the bottom two snaps and the rest of the flaps stay in place well enough.

It's definitely very warm and not appropriate for warmer weather skiing. I was looking for warmth and I'm using this for streetwear. When it's bitter cold I just want to be able to put on something really warm and not mess with umpteen layers. I generally leave the pit zips open.

The hood can be cinched on either side of your chin as well as at the center back of your head.

The sleeves do not have inner cuffs, which I was worried about, but I can snap them on the smallest setting without having to undo them to get it on and off, and I think it will be just fine.

It is heavier weight-wise than my last parka but doesn't feel heavy on me. The fabric does not feel too stiff. I can't test out the waterproof/breathability just now, but the specs are good and it has a good company standing behind it.

It has just a one-way zipper, which I prefer, but if you definitely want a zipper that can open from either the top or the bottom, this jacket is not the one for you.

I am so happy to get a new jacket with a unique design at a price I can afford!

UPDATE NOV 2015: I have had more than one perfect stranger compliment me on this jacket and I am totally happy with its looks and performance..

Nice jacket.  Good water repellent coating.  Inner liner can be removed and worn as a light weight jacket.  I was surprised that its not as warm as I thought it would be, but if you are active it will be comfortable.

very nice, used this 2 times now. I put this on top on my 0.5mm wetsuit to keep my body warm without feeling too bulky. I am a Small in most other international scuba brand, and i used xs BCD from Scubapro women, am 5'5 (165cm), 60kg. I ordered Large for this jacket, it fits well on top on my 0.5mm and a 2.5mm vest (total i have 3 mm under this jacket).

Really nice jacket. Kept me pretty dry while rafting down Grand Canyon. Zipper was a bit of a hassle, but overall the jacket looks sharp and looks well built. The jacket is also very light, which was a plus.

I am glad I picked this one over the others I looked at, including a couple North Face ones. Had great reviews everywhere, including the associate at the Sportsman's warehouse Store.

I would recommend buying this jacket.

I intentionally ordered one a little on the large side.  Jacket is very light and is water proof as billed since I tested it in a heavy downpour.  Hood is comfortably adjustable and does not blow off in the wind....also tested.

Geat wading jacket. Another great item from Sitka.

This is a very nice waterproof jacket.  Looks good, is quite warm due to lining.  Great jacket for winter in the Northwest!
