I have purchased Jottnar in the past and always been satisfied ... well more than satisfied and this was no exception. Package arrived safely ... kept informed re delivery. Baselayer is a good fit, kept me very warm on a recent walk out on the moors along with Jottnar down jacket. Excellent quality ... should last for quite a while.
Amazing quality, comfortable to wear. One of my favourite clothing purchase.
I live in baselayers, work in them, ride in them, run hike and climb in them, gym in them, and this one is an absolute beauty. Cant praise it highly enough. The detail is perfect. Feels so luxurious.
My wife is jealous and asks “when are Jottnar making them for girls, please?”
Great quality as usual from yourselves. Fits nice and very warm .very smart can even wear to pub
Unbelievable base layer and I’m turning into a jottnar nut. Was arcteryx through and through but now after last couple of purchases this is the brand i need.

This is definitely a cross over top it’s smart enough to wear on an evening out with jeans or trousers. I’m sure that it will be as good under a waterproof while hiking but I haven’t been able to bring myself to do that yet 😂 keep up the great work the kit is so good
Softer and more stretchy than the original version. Still a great fit for long arms. Slightly bulkier than most base layers, but works well as a light jumper as a result.
My wife bought me Heimdall for my birthday, 13th November, 71 years old! Beautiful piece of kit, feels great, looks great, really impressive. I will be wearing it out for my birthday dinner tonight and I will also be wearing it out when I go walking through the UK countryside. Many thanks, I will be buying another one soon. Lars
Great quality base layer, very warm. beautifully made with some lovely details, could be worn as a top it’s so stylish.
Just received this to add to my Jottnar Collection , I have to say first impressions it’s absolute yet top notch quality , the fit is super and material is fantastic !!
Outstanding design and materials make this a cracking piece of kit.
So Ive been waiting like Pablo for about a year for the Henning LX to come back in stock to no avail. Saw this and loving merino decided to get one in oat. Such a good top, comfortable, warm and looks great. Far better than my Fjallraven merino if you want an idea of the quality. Straight away ordered another in Blue, with the 30% off code that came with the first one it was a no Brainer. Jottnar definetly my favourite outdoor brand. The quality is unsurpassed.
I’m really pleased with my Marino Heimdall base layer. Really soft and comfortable piece of kit which I’ve worn in the fells. Great fit, not too tight and feels great next to the skin.
Another fine piece from the Jottnar team ... lightweight yet very warm when paired with the right outer shell.
Wore this whilst skiing in Alaska. Very warm, very comfortable, great range of movement, and no smell even after multiple days usage.
Well made, fit is snug but comfortable. Haven’t tried it yet carrying any load but the material feels soft enough not to rub.
Quality kit, keep up the good work
I was sceptical about how lightweight this was but as soon as you pull it on you can feel the warmth. Nice length to cover beyond lower back - I’m 5ft 10 and 83 kg and a medium fits perfectly. Zipped right up it keeps the neck warm and avoids needing a snood. Brilliant material, fit, feel and I think it looks pretty good too.
Outstanding quality base layer. I love this piece.
Very good weight to warm.
Bought mine pre prdered just as they were initially released last year I think with my njord.
The 3 stars are because I have found the label on the inside of the garment rubs on my skin and ends up being uncomfortable/leave red marks on my abs if worn for any period.
I don't wear it too often because of the above.
If it is cold however, I will wear a sacrifical layer underneath to take the brunt of the damage, as, even with the lower rating, the thing fits well, is comfortable (stand fast previous issue) and is high quality.
As per my initial remark; it could be an issue they have recitified in subsequent iterations.
A great top with a very high warmth to weight ratio - it weighs next to nothing, packs away small but you feel instantly warmer as soon as you put it on. I bought it for skiing and winter sports but I’ve been using it a lot mountain biking on Dartmoor, as it bridges the gap perfectly between a tee shirt and a thicker fleece long sleeve. It does fit quite tight though, I’m a 40” chest and 5’ 7 and I got a medium. This is fine for riding and exercise etc but if I wanted a slightly more relaxed fit I would have to go for a large.
I've a couple of these tops and my first choice whenever I head for the hills. I don't sweat or over heat in them and able to wear them +3 days between washes. It was a long Spring but now able to head for the hills as often as I like. One of the plus points from being laid off due to Corona!!

5ft 11 - slim build - medium fit is perfect.
So far used as base layer with windproof for chilly morning bike rides and works a dream. Also looks reasonably smart for other social activities
Amazing fit keep you nice and warm but not to warm which I think is down to the side vents looks good as well considering most merino tops look awful
Really like this top. Very comfortable and great fit with it being quality made.
Great customer service
Warm , comfy and well made . Best merino wool top I’ve used .
Really great kit
I ordered the Heimdall - it’s my second - because it’s an outstanding garment. The high neck and technical panels offer v high performance, heat retention, wicking and stretch. I recently skied with it in Alta, UT. It’s my go-to base layer and I combine it with my Alfar mid-layer. I ordered this second Heimdall after the UK government’s CV-19 lock-down and It was inadvertently delivered to my office when I was working from home. No worries said customer service, we’ll send another one to your home for free and you can return the other one when the lock-down is over. Now that’s class. Very much appreciated.
Fantastic bit of kit both fit and functionality and definitely recommend as best base layer I have bought
I love the fit and feel of it.
I have purchased a few base layers in my time... as someone once stated to me ... certain items you buy cheap and pay twice. If you ever have been in the mountains (skiing, walking or climbing) that can become true really fast. Jottnar base layers do what they say on the tin... yes Jottnar garments aren't cheap, but they function as you would expect. The only item I cannot comment on is the garments longevity, but if its like other Jottnar garments then it's no worries... thoroughly recommended... and Im not being paid to state this...!
