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.

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.


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.


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.

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.

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!

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

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.

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.

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.

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.

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.

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.

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.

Great jacket

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

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.

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.
