Asger Polartec® Alpha™ Hooded Jacket

Absolutely love this jacket. I have worn it throughout spring on cold days, cool windy days, warm days and it just works. I was impressed with its performance in the mountains over the last weekend up in Torridon. A mini expedition over 4 days on Beinn Eighe with mixed weather including some high winds and cool temperatures. The jacket protected me from the cold wind into the night with just a base layer underneath. I wish I had purchased this jacket years ago!! It will accompany me on every mountain trip from here on.

My wife bought me this layer for Christmas and it has quickly become my favourite bit of Jottnar kit!

I found this winter that it was warm enough to keep me snug (under my Odin Shell) but was quite forgiving regarding heating me up too much when working harder in the snow.

I also love using it as an outer layer when the weather is dry and it works well both stopping wind and keeping me warm when I only have a baselayer under.

It looks like a light down jacket but really it is a polartec fleece. I found it is a really good balance between warmth and being light enough to allow easy management of your temperature.

Only wish is that there was a inner pocker in addtion to the two outer waist pockets, but really that makes it a excellent (the balance of lightweight to warmth).

Love this layer :)

This is my first piece of jöttnar kit. Have to say, really impressed. It's replacing a Marmot jacket I've had for 10 years. Had an Atom LT hoodie too which is a solid jacket but this offering from jöttnar is excellent. Very breathable and windproof. Light and warm when it needs to be. Good job

I wanted a really good quality, warm and light fleece layer to wear but was almost overwhelmed by the range of items on offer from all the different manufacturers out there. I did loads of research but kept coming back to the Jottnar kit, mostly because it seemed to tick all the right boxes in terms of what I wanted. I was a little put off by the price but, working on the basis that "You get what you pay for", I took the plunge. I have to say that I was not disappointed.

I have worn this in Snowdonia in variable weather conditions. Climbing the Idwall Buttress in good weather, I found that I never felt too warm, but didn't get cold when we stopped moving for breaks etc. The very next day, on Tryfan climbing another grade 2 scramble, the weather was poor. The Asger handled wet clag with no problems. The wind was effectively stopped. When it came time to wear waterproofs over the top, the jacket kept me warm. All in all, this jacket is extremely effective.

Wearing the jacket with a climbing harness was easy and comfortable. The 'no-snag' adjustments at the sides meant that a snug fit was achieved and the jacket never got in the way or rode up.

I am delighted with the Asger, and am sure that it won't be my only purchase from Jottnar. I'll be wearing this with a Jottnar down jacket(which I've yet to buy) on forthcoming trips to Scotland for winter mountaineering, Kili and Island Peak and have full confidence that it will perform brilliantly.

Used this jacket as a mid layer in Bardufoss Norway in -20 and was impressed with it ability to keep my core at a comfortable level whilst working. Great piece of kit.

Great weight. Excellent as a mid layer. Used under a shell.
Also used in dry cold weather with the Asta gilet.
Excellent quality

A top midlayer. However, if Jottnar could upgrade it from 90 Alpha to 120 Alpha , strengthen the wrist cuff, and stiffen the hood rim it would be perfection!

This is the second Asger I have owned - gen 1 and 3 (if this newest 2025 version is a 3). The gen 1 was my absolute favourite go to jacket for everything. I’ve worn it layered up the depths of Norway to the butts of Barry Buddon and everything in between! It’s by far the best jacket ever when used in a layering system.

I’m now on the gen 3 and it’s everything my original has been and a few an extras to boot!!

Excellent jacket - buy it!!!

Absolutely fantastic jacket, quality design makes for a great fit.
Think and light but very warm.
Recommend

probably the best jacket I’ ve ever owned. Excels in the mountains. Been waiting for them to come back in stock worth the wait🙌

Just what I was looking for light, warm packs down small and looks great 👍

This is the best jacket I have ever owned, I live in it!

I have a old jokul insulated jacket , in a medium that fit brilliant, this new jacket is long on the arms and wide at the bottom, not what I was expecting from the fit previously, other than this the quality is excellent, can't fault it ,really warm for the wight and bulk, brilliant bit of kit.

I was looking for a light windproof jacket to replace an old Rohan fleece. I looked at many different makes before I came across Jottnar and I was impressed by the many good reviews. Needless to say I am very happy with my purchase! My first outing was a walk just above freezing and I could not believe how warm the jacket was. This will definitely be my go to jacket from now on and I am sure it will not be my last purchase!

Instantly became my go-to layer since purchasing. Extremely well made, well fitting, incredible warmth-to-weight ratio, teeny-tiny and packable. Highly recommend.

Light, warm, functional

This is the best jacket that I own and the first I reach for - on its own or as a mid layer in colder weather. Can’t recommend this enough

Bought as a replacement for my old Marmot Driclimb jacket. This item far surpasses that and my expectations. Warm enough for 3 season use and a great mid lay for year round use.

Great, versatile all-rounder. Light enough, yet warm enough. Fits true to size. I'm usually a medium in jackets/coats but these guys generally are a little larger, so I always opt for a Small. I'm 5'10", 70kg and slim build. Another brilliant addition to my fast-growing Jottnar collection. Not been disappointed yet.

Bought the Asger in a sale and got the light grey colour. Initially the colour was a compromise but I have grown to really like it. The jacket is lightweight, fairly windproof and shrugs off a shower with no issues. I have a 44” chest and large fits perfectly. I’m beginning to really like this jacket. Going to be looking at more Jottna kit in the future. Very happy with my purchase.

I’m hooked…. Best fleece I’ve bought for ages. Does what it says - lightwieght, breathable and great in mixed weather conditions. Have been trialing it on early morning coastal walks with the dog. Next stop the Lakes. Would definitely recommend to family and friends.

I’ve worn my Asger for scrambling in Snowdonia, winter mountaineering in the Highlands of Scotland, on Island Peak in Nepal and for climbing 4000m peaks in Switzerland. This piece of kit is consistently reliable and has never let me down. I wear a lightweight base underneath and never get cold, nor do I feel the wind. It's lightweight and packs away easily when its not needed. The adjustable hood fits easily over a climbing helmet and the pockets are well positioned so they can be accessed when wearing a climbing harness and rucksack.

A great bit of kit - I wouldn't be without it.

Brilliant piece of kit. I have two. Wouldn't be without them. Jottnar rules 👌

the best mid-layer I've ever owned. Great fit, warm, waterproof/windproof.

Great bit of kit, lightweight but surprisingly warm.

This is a fantastic alternative to a 700 fill puffer jacket. If you are out in the mountains for a day or belaying on a crag and need an extra layer to keep off the chill then this can easily fit into your daypack without taking up valuable space and weight.

I own a lot of Jöttnar clothing now and I cannot speak highly enough of it. I am a very keen hillwalker and find its warmth to weight ratio outstanding.
Most of my items I have had for years and they are still in excellent condition. The base layers and mid layers are light but so warm and the Odin hard shell is the best outer layer I’ve ever had. The Asger jacket is so warm and will repell light showers and dry so quickly if you’re caught out in something heavier.
The customer service at Jöttnar is like nothing I have ever experienced, they are so helpful and will bend over backwards to accommodate.
I will continue to purchase Jöttnar products as and when I can.

Having worn my Asgar in a number of extreme environments, I can confirm it remains excellent. Lightweight, compact, warm it is a must to have in the adventure wardrobe. Entirely suitable as a shell jacket when working hard - on the climb, or as an under layer - once static, the Asgar meets all requirements. As ever with Jöttnar- high quality build and fantastic quality.
