Warm, windproof and packable; Heiko is your dependable friend when the temperature drops or the wind picks up, cutting out the chill and keeping you comfortable during light activity.

The quilted Primaloft insulation keeps a low profile, making it easy to layer under a shell when needs must. And it is easy to stow too as Heiko packs into its chest pocket. The benefit of Primaloft synthetic insulation is it retains its thermal properties well even when wet – and it shouldn’t take too long to dry out either.

We’ve used a soft touch polyester fabric for the inner and outer, which feels great next to the skin but with a DWR coating it is still tough enough for the job at hand.

Great jacket

Love this jacket. Very warm, windproof and not bulky like other insulated jackets I own. Fit is great and it’s a very comfy jacket. Find myself wearing it even when I’m not out on the hills.


Very warm for such a light garment. I wear a thermal vest (or an ordinary t shirt in summer) then a trail shirt. When it gets cold I put this on , if it rains I put a goretex jacket on top, if it gets very cold I put a down jacket on top of it. With a pied d’éléphant I can bivi out even in winter . This clothing combination works from +40 to -10 depending on how many layers I wear. It packs up really small, is very light and is an exceptionally useful garment.

Super packable

This jacket packs down so small and is so light that it’s a brilliant piece of kit on any adventure. It’s really warm for the weight of it too - surprisingly so. It always goes on my bike packing trips but is also great on any wild camping micro adventures. I even pull it on when taking the hound out. Very useful and had my money’s worth out of this one.

A comfortable and lightweight three season jacket

I bought this as I wanted something a bit more convenient to put on than my Jack Wolfskin softshell when the temperature drops and there could be some precipitation about. I have the 0Hiro which is great due to the food and Primaloft insulation, but the pockets aren't the most user-friendly as there's nowhere to easily put your hands. As this is basically the same jacket, only without a hood or thumb loops, but with different pockets, it was good to buy this knowing how warm it would keep me.

Like the 0Hiro, this is really comfortable and fits as well over a thin layer as it does over something bulkier when the weather is very cold. A lot of thought has gone into the design as the hand pockets are in a very convenient place and the chest pocket is perfect for a phone or wallet. If you want to stash this in your camping gear, zip it up, put your hand inside of the chest pocket and start pulling out the jacket until it's all inside pocket. Once you're done, the whole jacket should fit easily into the chest pocket and zip closed – there's even a handy little loop so you can hang it from your rucksack or inside a tent. In this form, it would probably make a useful and reasonably comfortable travel pillow!

Basically, from the beginning of autumn to late spring, this is my go-to jacket on cooler days regardless of whether it's a dry day or if there is rain or snow in the air as it does very well with repelling moisture, so it's a perfect way to stay warm without making you look bulky.

As I wanted a colour to stand out, I chose the Jaffa and I'm glad I did as it's quite a muted orange, but bright enough to stand out amongst a 'natural' backdrop if something happens and I need to be seen.

I wish I had more of them

I love this jacket. I wear it everywhere I can. Instant warmth. Very, very comfortable to wear, soft against the skin etc. You don't have to react to rain like a vampire would to daylight. Ample pockets. Slimish fit. Packs down to a tiny size and weighs not a lot at all. Decent zips with those handy Alpkit toggles. Goes well over base layers and just as well under shells. It's a go anywhere use anytime garment and I really wish I could afford to have several (one for walking, one for biking, one for the pub, one for emergencies!)

Early days, but...

Bought a large Heiko for some extra warmth on Scottish winter hill days. Fits like a glove and has sufficient length in the arms - I'm 6' 2"+, and about 43/34 chest/waist. I could easily get another thin fleece layer underneath too, if required. Early days for a full assessment, but if today's outing to the Meall nan Tarmachan area is anything to go by, it seems pretty wind proof...as promised. I like the light weight and low volume too.

Heiko jacket

Received this as a Christmas present and it’s great. Both for a walk to the pub and a hike in the hills, keeps off the chill when walking. Dries quickly...another great alp kit product.

Flippin' useful!

I brought this as a treat when calling into the Hathersage store. It's very thin and very soft but very warm and flippin' useful! It packs away next to nothing a spares me having to carry a big fleece. Trusted and loved.

Very versatile

I used this on a MTB trip in Morocco where the weather was very variable. It was great for putting on straight out of bed in a bloody cold room or when stopped for lunch or a photoshot high up on a mountain pass. Very light and packable, and fits snugly up to the chin. The pockets are well zipped and placed. All in all, very happy with it.

Go to jacket!

I wanted a primaloft jacket without a hood and am so glad I bought this one. Really excellent quality - warm, light, keeps the wind off but seems very breathable. The best thing is that I never really feel that I have it on - it's so comfortable. Very reasonably priced and well worth every penny.

Great Jacket

Purchased this jacket from the Hathersage Store, went straight out climbing at Stanage in heavy snow and the jacket was superb. Kept me very warm whilst belaying and didn't restrict my movement whilst climbing.

Great Jacket

This is a great jacket to throw into your backpack for those colder days. It's lightweight, packs down small and dries fairly quickly if you're caught out in the rain!!
Fits well with plenty of arm length to stop them riding up. Thin enough to work as a mid layer too, which works really well. Casual enough looking to pop down the pub or shops.
This jacket served me well on a recent trip on The Tour du Mont Blanc and therefore highly recommend it.

the who
Good no nonsense jacket.

warmish jacket which will fits nicely into most peoples outdoor
actives. apart from extreme cold conditions, this kind of jacket
will get plenty of use from early morning commute to work, to
your weekends away trips to the countryside.

love the jaffa colour too. only thing to note ! the boffins at alpkit
should do a hood version next time.

very impressed so far

Didn't really need this jacket. I have a Patagonia Nano Puff Hoodie which was my go to thinnish insulated jacket. The Alpkit Heiko feels more luxurious and plush. This may be to the larger panel sizes that allows more loft for the insulation and material. It definitely feels warmer than the Nano puff.
Only worn a few times so cant comment on the longevity of the panel stitching, that always seems to be the weak point on this type of jacket.

Very Good and versatile

This has rapidly become my go to, do (almost) everything, warm layer.
I bought this to fill a gap- I have a heavier Primaloft Jkt for Scottish winter belay duties but that is often too heavy to carry "just in case" the rest of the year.

When walking and running I tend to run hot and very often wear a base layer and wind shirt only, through most of the year. The Heiko does a brilliant job as the over layer for stops or an extra layer if the weather turns bad and the going is too slow to keep warm. (I expect it to perform very well as the mandatory warm layer in the OMM kit list, striking as it does a good balance between weight and function). Walking with my 8 year old the pace is much slower and the extra warmth is welcome. Breathability is not quite what you'd want when working hard- but that's not what I bought it for.

For cragging it's the ideal warm layer- cutting out the wind and adding warmth when belaying. The hang loop when folded into it's pocket makes it easy to clip to the back of the harness (can we have a two way front zip for easier belaying on the MkII model, though, please).

It also gets pressed into duty as the quick grab daily dog walk jkt, and the post race warm layer for runs, sportives, triathlon etc where it works really well as a rapid boost when you can cool down quickly. Also partners well with jeans and trainers for the pub. Pence per wear, it stacks up as well, and often better, as anything else I own.

Cut comes up as expected (Medium): layers well over a base layer and fleece / under a shell if needed.

The death of the fleece

Brilliant jacket. Looked at loads of other manufacturers and always something wrong. The Heiko ticks all the boxes. Lightweight; the correct number and position of pockets; a drop back. I'm 6ft and 75 kg and bought the medium which is great as a mid layer once you pull the tabs tighter on the hem. Would have liked to have seen other colours available, a black or forest, but am happy with the Nemo. I can see me wearing this socially all the time in the British weather. I travel a lot and this will be my go to jacket to take away with me. If you do make some in not so climby colours I will get another. Time to get rid of your fleeces and buy one of these! Great delivery and service also. Cheers chaps.

Excellent jacket

Great jacket, good warmth/weight ratio, used it before/after ski touring and as a security jacket on the backpack. Packs good into chest pocket.
Good looking in orange, the S is not totally adjusted on me (1.68m, 60kg) but so it can be worn with 1/2/3 layers underneath.

Quality Jacket

I bought the Heiko at the beginning of January (2017) as I've been looking for a winter jacket. It was my first outing in the Peak District this year. With temperatures touching -3 degrees and a wind chill factor of -10 this jacket performed brilliantly. With just a base layer and a micro fleece underneath it kept the icy wind and cold out and I was comfortably warm. With its lightweight and compact material its well worth every penny.
I highly recommend this product to anyone, It's a Quality Jacket.

Dan M
Best for under shell

Recently got this jacket and can't praise it enough. Excellent on its own and will fit well under a fairly snug shell jacket. It looks too thin, but works well on its own. Top quality gear

Leroy Umbongo
Buy one!

I spent too long deliberating over buying other branded insulated jackets, and could not find what I really wanted. Luckily, I remembered Alpkit and their fantastic value for money gear. This jacket is awesome - lightweight, warm, well fitted and not over the top with logos and colour etc. Arrived quicker than expected too.
So if you're reading this having spent hours on the internet looking at over priced insulated jackets.... buy one, you won't be disappointed!

Fleece replacement

I bought this jacket with a view to having a lightweight jacket in my pack when touring in the Alps next year. Fleece warmth but with some wind and rain resistance. I've worn it over a T this winter when the temperature is just above freezing and it works perfectly. I bought my first bit of Alpkit earlier in the year but I've become a dedicated fan. Quality is top notch and at 188cm at last I get a jacket (xl) that covers my lower back. Great job Alpkit.


When it arrived and I saw how light and seemingly insubstantial it was, I was sceptical about how warm it would be but I have worn this at several degrees below 0, and with only a technical tee under it while on the move, and I have been nice and warm. They should have shown a photo of it packed as, when it's packed into the chest pocket, really is very small, and it immediately retired my bulky fleeces. Well done Alpkit.


I bought this in preparation for my first OMM. An excellent jacket, light and packs small. Will be using it on colder days at Leicester Tigers as well. Great value.

Solo Hiker
Nice Jacket

The material and stitching on this jacket seems of a good quality.
I am 6ft tall, average build with long arms and the large size fits well in the body and the arms.
It's my personal preference but I would rather use a stuff bag than use the pocket to stow the jacket away .
Over all I am very pleased with this jacket.

Handy jacket

Very good everyday packable jacket. As 3 layer top not warm enough but ok with extra gilet and an outer waterproof. Very versatile.

One of the best

Very lightweight but still manages to keep you cosy and blocks out the wind. Brilliant for travelling and can be packed down smaller if using a dry bag. One of the lightest jackets with this level of insulation you can buy. The fit is absolutely spot on, with a slightly longer back. (Med fit for me 5ft 10, 75 kg, approx 40 chest). The only prob is that there is a lot of stitching and some are now coming out, looks quite used quite quickly but not a major problem for me but the reason for four stars.

Didn't Buy But Tried On...

I tried on the medium and the large, each time over a full length base layer and a woollen jumper. The large was too baggy around the core, and the medium was just right. Unfortunately, the arms were too short for me: when raising my hands above my head my wrists were exposed by two inches with the medium, and the large was still short in the arms in this regard. The fit would be OK for hiking, but I wanted longer arms for scrambling and climbing. Such a shame because the jacket looks really well made and looks great. I'm 6'0", weigh 75kg, have 38" chest, and have long arms. I hope this review will help others choose the correct size.

tony harris
Great compact jacket

After a few months I really like it.

It packs down brilliantly and is plenty warm when layering in the cooler months or over a tee at when the sun goes down. It'll fit in a small bag no problems for 'just in case'.

However, It does shed its internal filling with alarming regularity. So much so that I almost returned it but obviously didn't because I liked the cut and utility well enough to test its durability a little longer. It still sheds its filling but I will be testing it hard on the trail in NZ later this year.

I tried to buy my wife one - she was disappointed as it seems that Alpkit is following the gender styling industry trend of making items in 'ladies specific colours' like purple and lavender. She wanted a steel grey one like mine.

All in all. Good jacket.

Tromso Split

I have just spent a week splitboarding in Arctic Norway. I used the Heiko every day to throw on over my skinning clothing to keep off the chill on the summits and to board down in. The jkt is perfect for hard working mountain days where you need a lightweight insulator when a down jacket would get wet, or simply is not tough enough. The longer tail is great under a rucsac and the simple design and cut ideal for what I wanted it for. The face stitching could be tighter as it got caught on my cheat sheets, but this is not a piece to be precious about but to use and I did, very good

My most used jacket!

I commute to work by bike wearing this jacket for a good 6 months a year, any time it's below 10C I reach for my Heiko. Surprisingly warm for a very thin jacket and has a lovely soft liner which feels great next to bare arms. The collar is nice and snug, stopping any wind getting in. My only complaint would be the outer fabric lets the insulation through, so after a few months use you have lots of tiny white tufts showing, also the zip pulls are too stiff and keep undoing and I've lost nearly all of them after 6 months use.

Ian Wilson
Surprising cosy, lightweight and versatile.

I bought this about 4 months ago paying about £60 for it. I wanted something to use as warm layer during pauses when mountain biking and hill walking. It packs fairly small and bounces back when needed. Like others I have found myself reaching for it when I'm off down the pub or just taking a turn round the woods as well as when it's needed for expeditions.

It isn't super-warm, so anyone telling you they slept outside at Everest base camp wearing only this and a cashmere thong is prone to exaggeration. But it has the same feel as down in the way it instantly cuts heat loss whilst feeling light to wear.

It is also great if you need to break wind when you're on the hill. I've worn mine in about 40km/hr gusts and it's pretty impervious, cutting windchill substantially.

I haven't really tried its wet-warmth capabilities but, it being synthetic, I stress less about it than I would natural down.

Fast becoming a favourite jacket, then. So, why 4 stars not 5? Well, there was a fault, quickly fixed at a cost of £6 by Alpkit (but shouldn't have been necessary) and at the full asking price of £95 there's a lot of competition and personally I think that is starting to push the end of the value envelope.

warm jacket for the price

Only worn a few times but already proved useful. Proved it is windproof in the British climate and plenty warm enough. In fact for the weight and thickness of the jacket it is very warm. The jacket is will made although there are a few loose threads which could be finished better. Overall a great jacket which will prove a good purchase.

Frodsham Dad
Great jacket

Lightest, warmest jacket of this type at a price that is great. Well done Alpkit..

Good but not perfect

Price wise this looks a no brainer compared to Patagonia. First impression is positive however after a couple of days wear there are signs of the synthetic filling coming out through the stitching. Nothing too significant but worth bearing in mind.This has not happened to my ten year old Patagonia Nano Puff despite hard use.

Great jacket - but be aware

As with the other reviews, I can't really fault this jacket in terms of what it is designed to do - keep you warm, works great on its own, yet thin and light enough to work as a mid layer without making you sweat too much out on the peaks.
My issue and therefore average rating is based purely on the quality of the stitching on the loop when the coat is packed away. I had the packed jacket attached to the outside of my backpack for easy access during changeable weather on the Tour du Mont Blanc. Within an hour of light walking the loop had snapped and the jacket was on the floor. If I was the last in our group I would never have known it had fallen and would've been without an important mid layer for the next 10 days.
I don't think it being attached to a backpack whilst walking is an unreasonable expectation, hence the review.
That aside,a fantastic jacket, just be aware of this potential flaw.


We have contacted Craigo as this sounds like a stitching issue. The loop is designed so that you can clip the Heiko to your bag or harness and shouldn’t break from this kind of use.

Good & Bad

Really liked the jacket initially - it's very warm and looks good , I use it to walk to work and it performs even when very cold without a top layer.
However, I've only had it a couple of months - not done anything rigorous with it and the sleeves have stretched a fair bit which is a real shame and annoying. Maybe because the sleeves are made up of two parts and stitched together?
There are plenty of other options at this price, I really like Alpkit, so wish this was better. I don't want a jacket that stretches out of shape so quickly (or at all).

Pete Smith

The Heiko jacket is ok!! don't get me wrong it is light weight, very light weight. The materials are, well not that good in my opinion anyway. 10 days of easy, casual wear and the cuffs are showing wear already the collar looks stained by skin oil - I am not even oily grin (See pic attached of cuffs) It is not as warm as I had hoped and would benefit with just a little more filling. I guess I will see how it wears over the next couple of weeks, in such a short use it is not so great sadly..........
