Thorsen Lightweight Down Jacket

£299.00
Regular price £299.00

High-loft lightweight down jacket with superb warmth to weight performance.

Filled with 850 fill power hydrophobic goose down in a 93/7 down/feather ratio, with 100g/m² synthetic fill in the cuffs, collar and shoulders for durability where insulation compresses most and moisture builds. A 20-denier micro ripstop nylon outer, woven with Bureo® NetPlus® 100 % recycled net and finished with a PFC-free DWR treatment, resists wind and light moisture.

Thorsen's water-repellent down stays dry far longer than untreated down, won't wash out, and complies with the Responsible Down Standard. Zip guard, hand warmer pockets with front-facing insulation and internal valuables pocket. Separate stuff sack included. Also available with a hood - the Fenrir. Scroll down for full details.

Sense of freedom

I’ve been down on the coast trying out the layering with Thorsen and Magni. It’s great. Soft, lite and so warm. No sweat and I love the lightness. It’s gives a sense of freedom. Await the merino beanie.
Jacket is XL so didn’t want too tight a fit. Await more cold weather. Great new brand for me to add to other favourites: VivoBarefoot, Elliot Brown and Nomatic.

Thorsen and Mjolnir

Now had both of the items for a couple of weeks and am very impressed with the fit and quality of each.
It was particularly pleasing to have bought at a time when the jacket and hat had been reduced in price for a short period.
Will now check the website regularly.
Just a quick “heads up”, leaving this review was not as straightforward as it might have been.

Thanks and regards - Mick

An amazing jacket - perfect fit, warm and super comfortable

I recently bought the Thorsen jacket in large and found it to be a perfect fit since I don't intend to wear any layers beneath other than a t-shirt. I'm 6ft 3", 95kg, broad shoulders with athletic build. The description says it is a "standard fit" but for my build it is more of a trim/fitted fit which suits me fine.

The technical stretch cuffs - which are very similar to Arcteryx Atom LT (and old SV) cuffs - are also a nice detail to prevent loss of heat.

I also bought the Fenrir large but returned it since it felt a little too tight across the shoulders.

If you want a quality down jacket which is incredibly warm and comfortable then look no further than the Thorsen jacket.

This is my first purchase from Jottnar but it won't be my last!

Almost perfect

Already owning a Fenrir I knew I was getting quality. Bought the Thorsen for use when it’s cold but not cold enough for the Fenrir (which is too hot in double digit temps) and it’s been great the last few weeks. I’m 6ft 13 st and wear a large. Cuffs are very good. Could only be improved with a net style internal pocket like my Fenrir which I find very useful, otherwise perfect.

2nd time down purchase

This is the 2nd jacket I have purchased as I get so much use from my initial fenrir purchase.
These are quality put together items you can feel the quality in every aspect. I am 5ft 9’’ and 78kg a medium is just right. It also fits my son who is 6ft 1’’ and similar weight. I tried the Orian blue but returned it as I liked the circuit blue better- customer services are superb
I have 8 jottnar items and have now switched from Arcteryx as I prefer this brand

Awesome Jacket

My Thorsen jacket arrived last week. It’s a great colour (Orion Blue) I ordered large, and it came too big. The medium is perfect. The customer service was top drawer for the exchange..
The jacket is really lightweight and great quality… I’ve had a few other brands, this one is pricey, but well worth it ..

You get what you pay for

Great quality warm jacket packs down real small into its own attached bag and springs back well when you unpack it. Good feel and fit pockets and zips all good

Great Jacket

Jacket is very warm for its size and weight - incredibly light, soft and packs into its own stuff sack making it ideal to put in a day pack when hiking “just in case”. Slightly long in the sleeve but this also means it is easier to layer. I am 1.8m 80kg and bought the medium which fits me well. Definitely recommend - it is certainly a step or two above my Rab equivalent.

Smart good fitting

The Jottnar Thorsen is a splendid fit very smart and very warm I am very impressed with the quality, currently trying to convert my wife to the name I’m sure she would be very pleased..

A+

Jottnar products are first class, excellent quality and attention to detail and very warm. My only comment on the Thorsen Jacket is that it comes up fairly large. I have a medium in the Fenrir which fits perfectly and had to exchange the Thorsen from a medium to a small. The Thorsen is also more of a 'boxy' fit. Great jacket though. Highly reccommedend!

Perfect warm lightweight jacket

I bought this jacket for my husband for Christmas and it’s amazing. Really warm yet light as a feather and ideal for walking on these crisp January days. It’s smart yet casual and nice length (not too short). Great jacket!

Amazing

I got my Thorsen jacket and I wear it everywhere. It is really a great jacket.
I did get mine in a sale and that made it more affordable as prices are a little high. Can't escape the fact it is an amazing jacket.

Thorsen Jacket

Awesome product, really warm. It’s the anti snag zip detailing that helps when wet trying to zip up pockets, nice cuff details. Good size chest pocket which can fit a folded laminated A4 map.
Good length in the body and sleeves. Sizing is larger than other brands my other jackets are XL, the large in this range fitted perfectly. Best jacket ever.

Quality garment

Ordered the medium after reading the reviews when I would normally go for the large. Proved to be correct size. Comfortable, warm jacket which will serve me well over the coming months.

Hoofing bit of kit

Needed to replace my old down jacket and decided upon the Thorsen. Great bit of kit well made and great design details. I would go down a size as I normally wear XL but went L after reading other reviews and it fits perfect. Fast delivery and great customer service will be using Jottnar again

Fabulous jacket

I bought this jacket for my husband and after reading reviews I ordered a M, very happy with the jacket but a little on the snug side for my husband so thought I would give the jacket to my so-in-law and order a L for my husband. Went on the website and the jacket was no longer on sale, I emailed customer service and told them my problem, they were absolutely fantastic, very prompt response and sent me a code so that I could get the 2nd jacket at the sale price. Now have 2 very warm light weight jackets and 2 happy men. Customer service was excellent, order and delivery very quick. Would highly recommend this company.

Not athletic fit, more like a belay jacket

Most Jöttnar gear is tight fitting athletic fit and works well on me (quite slim physique 5 feet 8 1/2 65 kg usually size small) however I’m able to wear this over two base layers and an Atom LT Hoody plus a Floyen jacket on top and it’s still not tight on top of all of that so when I wear it with less it definitely holds plenty of air underneath it but slightly baggy compared to other kit.
It’s not a heavy duty down jacket, pretty light and packable so not as snug fitting as other similar garments I own. Kept it as something to take out when cold in other layers and need an extra layer.
