Fantastic jacket

I bought this jacket a couple of years ago for a winter trip to Norway. It’s been such a good jacket, perfect fit and very warm for it’s weight. Also used it as a mid layer while working the season in Antarctica where it performed very well. Definitely recommend this jacket.

Very happy

I've had a few Jottnar products and they have always been fantastic quality and very practical so I was expecting the same from the Fenrir down jacket and was not disappointed. I've had owned down jackets from North Face, Arcteryx, Montane and Rab and I can easily say that this is the best, great attention to detail and fit, nice length and very warm. The fact that we run an axe and knife throwing centre and one of our ranges is called Fenrir is just a happy coincidence.

XL FENRIR

I got this jacket for outdoor life and work. First off I am 6ft3 44/45 inch chest. the XL is the size for me. It’s. A little tight around the waist/hip but doesn’t interfere with what I need to do. Incredibly warm and packs away nicely in the bag provided. Took it to the Lake District last weekend and kept me warm at night. I am taking it to Iceland in October, but also can’t wait to wear it to stay warm working outdoors. Fits great under my hardshell jacket.

Fenrir! Could it be the best!

After doing much research and messaging Jottnar who were super helpful and vital in my final decision. I settled on the fenrir as being suited best to my needs. This is the second piece of jottnar I've bought and once again i wasnt let down. I chose the night shadow colour. The fit is perfect I went for medium and I'm 11st 5.9 tall. The quality is high and feels light to wear. Combined with a small base layer today on a walk in a temp of 5 degrees but with a harsh wind I was super warm and impressed. The hood is a good fit and the pockets are perfect to stash gloves and keep your hands warm. Internal pocket is of good size and should take all modern day phones. Zips are of good quality too. Overall totally pleased with my purchase. Well worth the extra money! I've also experienced no down loss yet! Cant wait to use it on the mountain after corona!!!!

First time

I was looking for a lightweight warm but packable jacket to use as part of my layering system for my EBC trip in February. Just tested it this week in the Lakes and I am very impressed. It will not replace my super warm Hagloffs but it will be my constant travel companion to wherever I go.

Top quality jacket well made for sure

Unfortunately the Fenrir was not what I was looking for I have found that in the Floyen jacket though

Much improved jacket

I had a Fenrir jacket for about 5 years, and decided time for a new one.
Well what a difference the improvements have made
The fitting is much more athletic, the hood much bigger, longer at the back, and extra baffles

Fantastic quality; slightly tricky fit

The jacket is excellent quality; lightweight and the waterproofing seems pretty good so far.

The down is quite thin and I must admit I was expecting it to be a slightly heavier weight, but given the thickness it does seem quite warm (similar when comparing this to my old Icebreaker down jacket that had merino fill).

My main 'issue' is the fit. These jackets all seem to favour 'thin' builds. I am a 44" chest, 32" waist and just over 6ft tall. A large is too tight on the chest, and the XL I have to cinch quite a lot to get it to 'seal' at the bottom and keep in the warmth. It isn't a problem unique to Jottnar, but I had been hoping it might be one they had catered for.

All that said, I am very happy with the purchase.

Toasty!

I bought this jacket for a trip to Finland in winter and even though this is a lightweight jacket it was plenty toasty for the -5° to -10° we were experiencing. Beautifully made with plenty of great details.

Superb quality

Well impressed with the product that is well put together. I did a lot of research prior to placing an order with Jottnar. Very pleased with the product. If in doubt, BUY!!

Great bit of kit

Just what I needed, jacket where I can just wear a t shirt under, would purchase more of this brand, highly recommend

Beats the big names

First jacket from these guys replacing a very well worn Rab (8-9 years old).
Typically have defaulted to Arc for costs but the last few years there’s been such a decline in their quality.
Fit wise, a medium for me was spot on. 6”2, 39” chest, 33” waist.
Subtle features especially in the cuff are brilliant. Additionally the water resistance has held up even when strong winds present too.
Very hard to fault the jacket at all in fact.
You’ve got a new loyal customer for sure

Quality Kit

Lightweight and warm without the bulk. Fits well and if its seriously cold or wet can be worn under an outer without feeling restricted. Keeps dry after shower and dries quickly. When outside for period of time in the cold others are gibbering but Fenrir still toasty. It just works.

As good as I hoped it would be

Love everything about this jacket so far . Fit is perfect and quite tailored . It is very warm when 0-10degC . Also seems to be slightly more water resistant than other down jackets I own. Helps that it also looks great !

Lovely Jacket

Just purchased the Fenrir Jacket and very impressed with the warmth, construction and overall quality of the Jacket its definitely up there with the Best on the market, my only gripe is its a little short in the arms length for me an extra 2cm or so and it would be perfect, overall tho a great winter Jacket.

2 Fenrir's are Better Than 1

Pertex Quantum Pro is an upgrade on the original but otherwise the usual Jottnar quality with this, my 2nd Fenrir. Im 6ft and 70Kg, small works fine for me.

Excellence as standard

I don’t expect anything else from Jottnar now. A customer for life.
Super lightweight, looks slick too, not a bulky boxy duvet cover like the rest of the market. Top class as usual

Excellent!

Superb light weight jacket. Warm and fits really well, unlike some down jackets. Highly recommended.

Awesome!

Super happy with this. Very comfortable, lightweight and warm. Yes it's expensive but worth it due to the sheet quality. I also lo e the fact it's not a really well known brand so you don't see them everywhere. Can't fault it.

Excellent quality

My first Jottnar piece. The quality is very good and overall I'm very satisfied. My feedback would be why can't you have a double zip? Also the neck is a bit annoying if you don't have the hood up. I like to wear it zipper fully up but the hood is then not very comfortable forced against the back of your head. I've then tried to wear it with a scarf to be more comfortable but because this also doesn't fit well due to the shape of the neck. Still happy but fix these things and it would be the icing on the cake :)

Customer
Fenrir Is 5 star !

I am very happy with my purchase of the Fenrir Jacket. I was looking for something that was smart but compact and able to keep me warm without wearing lots of layers underneath. The jacket is very high quality as you'd expect from this brand and does not disappoint. The customer service team were brilliant pre sale and advised they could post out next day. I would 100% recommend this product. I wore it on a recent trip to Scotland at winter time and only wore a t shirt underneath where the temperatures were single figures and I did not feel cold at all. I purchased a large size and have a 34in waist and 42in chest, 5ft 10 medium build.
I won't hesitate to purchase more from this brand. Thank you.

Men’s Jottnar Fenrir Large

I am like the Jottnar founders ex military, and over the years I have purchased and worn a number of different brands of jackets, but this feels superior. Very professional setup, from the outset instant and helpful email. I ordered on the Friday and I was kept informed from the outset, delivered two days later on the Sunday, while Evri gets some bad press , I also found them very professional, Morgan was very helpful. For the record on size which was my only concern, I am 12 stone 7Ib , 5.ft 11in, 44 inch chest 16inch neck , slim gym goer and the large fits perfectly. Very pleased. Would thoroughly recommend.

Outstanding quality

Ordered size Large as I take Large in everything and already own a jottnar coat in large . Unfortunately the large , although fits perfectly everywhere else was slightly tight under the arms when i reached out so had to return it . Tried XL but looked too big , was so disappointed as the quality looks absolutely amazing and really wanted one . Not sure why it was tight under the arms though . If fitted would give a 5.

Fenrir 2025

Fantastic jacket, bought the forest green. It has a lovely soft feel to the outer. It’s compact with good detailing. Originally bought the medium it was a bit too small returned it for a large so much better. Great customer service very quick and easy.

Nice up grade

Bought the newest version to replace the one I have had for many years. Same size(XL) I feel it’s very slightly a roomier fit, in the body and more snug around the neck head area which for me is a positive comment, also more warmer feel when wearing. I can not comment about how waterproof it is yet .( which was a problem with the last model)
Overall pleased with the purchase.
