Fjorm Hydrophobic Down Jacket
Our warmest hydrophobic down jacket, built for deep cold.
Fjorm has been polar-proven by endurance athletes in Antarctica, the coldest continent on Earth, built to overcome extreme cold and punishing wind-chill.
Filled with 850 fill power hydrophobic goose down in a 93/7 down/feather ratio. Box-wall construction through the body and hood maximises loft where it's needed most. A 20-denier micro ripstop nylon outer, woven with Bureo® NetPlus® recycled net and finished with a PFC-free DWR treatment, keeps the elements out. Synthetic fill in the cuffs and collar for durability where insulation compresses most.
Helmet-compatible, down-filled hood, oversized internal dump pockets, two way zip, and a separate stuff sack included. Scroll down for full details.

Bought this as a good belay jacket and wanted something box walled and fairly long as I'm tall and alot of belay type jackets come up abit short.
The design and build quality is very good. The mix of synthetic and down insulation works well. I would maybe like to see some of the synectic padding in the nape of the elbow as it the down can move around and get a cold patch.
Otherwise it's got the best hood I have ever used and the box walls are full of down it's a great jacket and I have used it on numerous trips to Scotland, Germany etc. it's never let me down and it packs down well.
The mesh pockets are great for gloves and the fit for me is great XL and I'm 6'4.
True to size, lightweight, excellent warmth, looks great.
Very warm, very comfortable and looks great. Seems very good quality and made to last. True to size.
As a relatively long-term afficionado of Jottnar and the proud owner of among other items, the wonderful Fenrir, I took the plunge on the Fjorm. Primarily to replace a style over substance North Face parker (neither overly waterproof, windproof or warm). It's main use intended to be cold South Coast days/nights, (whether a walk along the beach or a walk back from the pub!), sitting in a cold football/rugby stadium, watching my kids do sports at the weekend stood on cold sidelines, AND of course my skiing trips - not for the pistes (for which I use a Floyen under a hard shell) but for cold nights around town, or apre-ski.
As one might imagine, it copes with the South Coast walks incredibly well - probably too well. I certainly wouldn't use it for real exerting walks on the Downs. Once you generate a bit of heat it's going nowhere in the Fjorm! Caught out in a shower, again, it didn't seem to worry the Fjorm, it's thick enough to offer some protection, and the hydrophobic down keeps its shape, a good level of insulation and dries super quick.
A cold winter Saturday afternoon at Fratton Park or Twickenham? Fjorm laughs at the chill. If only Jottnar did some nice Fjorm based Boxers to keep your bum warm!
The real test was Chamonix in January with evening temps down to -6 and up at the Aguille du Midi around -16. The cold didn't even begin to make a dent (underneath I just had a T-shirt and a micro fleece). This is a jacket that wants to mother you and keep you cozy and warm - and succeeds admirably. I've been to Tromso and sub -25 degree temps, and I have little doubt Fjorm would just shrug and say "Is that all you've got?".
Like all Jottnar gear it's designed to look good - and does - whilst having the substance some other manufacturers fail on. Yes its expensive, and yes you can find similar looking jackets cheaper. But look at the detail and you can see where the price differential comes in. Indeed you can find equally or more expensive jackets without the attention to detail. You can really feel the quality with the Fjorm. And just those small things that show attention to detail like the small circular disc at the bottom of the zip that makes it easier to zip it up (hard to explain!).
As someone who generates a lot of heat, I probably won't use it as much as I'd like and the Fenrir gets almost daily use. If you live in colder climes than South Coast England or walk/climb in the Lakes or Cairngorms etc, I'm sure you can get a lot more use out of it.
On a final practical note, I'm 6ft with a post Xmas weight of touching 15 stone (now declining!) and the Large is perfect (as indeed it is with all my Jottnar gear).
Should also add, that (and those who have already bought Jottnar will probably know), customer service is excellent. Any questions are answered promptly and knowledgably.
Hi Chris
Thanks for such a detailed review. It's rewarding to have your feedback after the sweat and tears that go into developing and building the Fjorm. The Fjorm has been in our range since we started Jöttnar and many iterations and much testing later, we're delighted with its 2024 'Glacial' edition just released (Feb 24).
This from you resonates with me particularly, 'The real test was Chamonix in January with evening temps down to -6 and up at the Aguille du Midi around -16. The cold didn't even begin to make a dent'. Love your Tromso aside too - I HAVE been in Tromso at -25C and wish I that I could have had the Fjorm then!

I have this fjorm jacket and also the asta gilet, both items are fantastic. The fjorm jacket is a lovely fit and keeps shape very well. I have had both for over a year now so as to give an honest review based on being used for at least one winter season. The gilet is my go to jacket for pretty much everything throughout the year that doesn't involve longevity in hills, heavy rain, mountains or stints in colder weather and is perfect for pottering around in, going out for walks if the weather is kind or just going to the pub. The fjorm jacket is perfect for colder activities and days. The hood is great and well insulated and also keeps shape, and neither have lost any down over time. The only slight issue I have with the fjorm jacket is that when the hood is up, the lapel in front of the chin/mouth can be irritating until you've found a way of moving it somewhere out of the way. But that is a small gripe, although in really cold temperatures way below zero I'm not sure if this would cause cold air to get in. But for me, it's been a fantastic investment. As has the gilet.

A very heavy duty jacket for the coldest days on the hill in Scotland and beyond. Very very warm. Very well designed and has a great hood and storage bin pockets. Sheds moisture and snow well, but best for very very cold conditions usually found outside the UK or on Scottish winter climbing trips

Good fit with room for base layer underneath if required. Lovely and warm and comfortable. My second jacket from these guys and it’s come with quality as expected.
I am normally a XL in Jottnar, but sized down to L for this. A quality piece of kit and super warm - too warm for anything this year...yet. Simple, well made and feels robust.
Good fit. Warm 275g of hydrophobic 850 Fill Power. Used in Scotland in howling winds and was nice and toasty. When it rained jacket beaded. Zip zipped up to the neck and when used hood was well protected and warm. Design of the cuffs is good, plenty of pockets for storage. Nice piece of kit that keeps the elements out. Lucky enough to of purchased in the sale, bargain.
Really pleased with fit ,quality, look and feels great and super warm can't really think of anything negative will definitely explore there range.
I look forward to winter wearing this jacket.
This is my 2nd FJORM jacket, the 1st lasted well over 8 years.
Great Jacket, material design and look.
Jottnar is a quality brand, a cut above the rest.
Picked up at a fantastic price with a 40% sale also.
Already own a Thorsen jacket. Wanted a warmer jacket for when it’s cold after swimming in the sea. So looking forward to using it this winter.
i spend all my working day outside standing on the atlantic coast of northern ireland. not moving.
it's amazing how cold it gets without keeping the blood pumping so i needed a warm shell to stay in the game.
Fjorm does it, thanks.
Just to put this in context, I am 5.9 tall and weigh in at about 158 pounds (or 11.3 stones in the UK) on the scales. This means I am very slender and medium-sized, so I have purchased the medium-size option of the Fjord down jacket. I have made other purchases in the past and Jottnar sizes seem to run a bit big. My medium size fits OK, but just because I am so slim, the jacket feels a bit roomy. I guess it all depends on whether you are going to be layering or if you want a snug fit. Taking this into account, I do not think it is a bad idea to size down depending on your personal likes and dislikes, or your body weight if you like. Having said that, I like the jacket. It is quite puffy and it looks as though it will perform well in below 0 conditions. The hood is quite roomy as well and will allow you to wear a hat or a helmet. The jacket comes with an inside pocket and a drawcord to make it tighter around your waist. All and all I am happy with this purchase and I do not think I am going to size it down.
I just received the fjorm today. Obviously it’s not anywhere close to being cold so I couldn’t try it out, but I did go over it in detail, and I can tell it’s made with superb quality and care. It fits like a glove, not too tight not too loose. I got a medium. I’m 5’9.5 and 200lbs. It’s so light and warm. I tried it on and within a few seconds I was sweating. The hood looks to be the best design and highly functional and protectant. The zipper is smooth like butter. Just an effortless glide. The cuffs have the perfect amount tightness around my wrists. And the color is beautiful. Also, it took about a week and a half for it to come in the mail. It actually came 5 days earlier than tracker showed. I will give another review when I get a chance to actually use it in a couple months. Thank you Jottnar for creating a masterpiece.
This is by far the best quality down jacket I’ve ever placed on my back. The first time I’ve explained a jacket as stunning in all areas but this one is and the best thing I can’t wait to put it to the test 👍🏻
The Fjorm Jacket is very robust and well made. Very comfortable and great in extreme temperatures. Far better value for money than some "Canadian" brands!
Just a beautiful jacket, these guys never disappoint such high quality products.
My sixth item from jottnar and yet another great product
I’ve had a number of Jöttnar products all are superior to many of the big brands out there, high quality, great design and performance is incredible. Fjorm is one outstanding jacket.
awesome great amazing
Didn’t expect anything else, top draw……fit, fiction it all works, would definitely recommend
I could’ve done with this jacket during the Battle of the Bulge.
Jokes asides, looks and feels
great and it’s so warm, probably a little too warm but if I look after this jacket it will last me years. Good job from the bods and Jottner and will be adding more to my kit and equipment.
“ We’re paratroopers Lieutenant were meant to be surrounded” 😉
I bought mine several years ago, and I’m still grateful to myself for making the choice to buy it!
My friends comment on how light it is, and I keep telling them, ”It’s not a warm jacket, it’s a feeling of warmth!”
Very happy 😁
Ordered yesterday 11/01/23 and arrived just over 24 hours later, brilliant Courier service. I have several Jottnar pieces of clothing, all are top quality. Yes this jacket is expensive, however, as with all Jottnar kit, you get what you pay for. I ordered a medium in black and I am 5ft 11 medium build. It fits perfect. The quality is superb. Is it warm??. If you wear this in temperatures above about 10 degrees you will lose about 3 stone in sweat. Even with just a t-shirt on underneath with outside temp about 7 degrees, I had to unzip it after about 10 minutes. Congratulations guys on making a fantastic jacket.
