A very lightweight and breathable loft jacket with Climashield insulation. Packable enough to fit right in your trousers cargo pocket. Designed for use as an insulating mid layer under your regular field jacket, can also be used as an outermost layer during static breaks or other light activities.

  • Relaxed fit, sized for wear over base/mid layers
  • Breathable and quick drying
  • Elastic cuffs and adjustable collar and hem
  • Long hem at the back
  • Articulated elbows
  • Zippered breast pocket
  • Weight: 405 g (Medium Regular)
  • Pack size: 10 x 20 cm (Medium Regular)
  • Materials:
    • Fabric: 100% polyamide
    • Insulation: Climashield Apex 67 g/m2

The L3 is primarily designed for wear as an insulating layer under your field jacket but also functions when donned over your other clothing as a quick means for extra warmth when pausing for a break in cold weather. Thus the simple design, very low profile and one single breast pocket on the left hand side, easily accessed after opening the front zipper of any jacket worn over the L3. The construction and insulating properties are comparable to a modern lightweight summer sleeping bag.

L3 - Insulation layer

The third layer of the Särmä TST clothing system, designed to be worn over a base layer of merino wool and under a field uniform or other outer shell. L3 garments come in two styles, unlined wind wear and lofty thermal wear with Climashield insulation. Lightweight, quick drying and highly breathable fabrics guarantee effective moisture management and great packability.

Take a look at our Särmä TST Clothing System!

Pro-Tip: The L3 is also a clever choice if you want to extend the temperature range of a lightweight sleeping bag, just use it as a thermal pyjama! The materials and construction really serve this


Shell and liner: Calendered 60D, 58 g/m2 100% polyamide ripstop. Very lightweight, quick drying and really strong for such a lightweight material.

Calendered? Calendering is a process in which a fabric is hot pressed to seal it´s surface. The effect is basically the same when you use a lighter to burn the end of a cut piece of cord. The heat basically irons the tiny fibres flat thus making the fabric very windproof and somewhat moisture resistant. Calendering is a good alternative to PU-coating when you need added protection from wind and moisture but still want to keep the fabric uncoated for the best possible breathability.

Climashield Apex 67 g/m2 insulation. This is some of the best insulation there is, fantastic weight-to-insulation ratio and great performance even in wet conditions. Apex is a continuous fiber filament, this means it does not need any attaching stitching like you would find on common polyester or down loft garments. By eliminating these stitches we also eliminate possible cold spots, further adding to the insulating properties of the garment.


Sized to fit over warm mid layer clothing without being tight but staying lofty enough to function as insulation. If you wish to use the L3 jacket over all your gear we recommend simply measuring your chest when wearing the gear in question and picking your size accordingly.

I also own a similar model from Carinthia. Nearly identical in terms of function, super warm, and much cheaper than the competitors. Put it on over a t-shirt and within seconds you can feel the warmth it provides. Great cut - mediums are usually quite tight in the shoulder area, but the medium for this jacket fit me well, with enough room to move my arms about unrestricted. The only downside is the lack of pockets, but for a jacket this good, and at that wallet-friendly price, I can live without them.

Tilasin het! Vaikutti erittäin pätevältä villapaidankorvikkeelta, kevyempi ja kuivuu nopeammin, sekä menee pienempään tilaan.

Käyttökokemuksia kun saan raportoin lisää. Housutkin tulossa, mikä on erinomaista.

Kokojuttuja taas. Olen 193 cm ja painan 116 kg. XL-long oli juuri sopiva takin alla pidettäväksi, eli tämän alle mahtuu vielä Leka Merinovillahuppari XXL ja Leka Merinovilla T-paita XXL. Päälle sitten Leka Windproof Smog XXL-long. Kesällä huppari jää tietty reppuun ja tämä toppatakki varmaankin kotiin. Mutta toukokuussa otan molemmat mukaan Karhunpolulle Lieksaan.

Even if you dont want to subscribe to Varusteleka's SarmaTST layering system, this is a piece of gear which I would suggest making part of your layering setup for a backpacking trip in the wildnerness. This jacket functions on the same principals as a sleeping bag, working to create a cushion of insulated air to keep your upper body warm. The jacket itself is incredibly comfy. The poly-ripstop material the jacket feels like material sleeping bags are made out of. This is a good layer to keep either in the top of your ruck, or somewhere else you can easily get to it when you come to a stop and start to cool down. The jacket is also great to sleep in.

It is sized generously to fit over other layers, for example I have had no issues throwing this on over a plate carrier.

I would however suggest keeping it away from an open flame, or rolling up your sleeves when working around an alcohol stove. This will melt if exposed to high heat, but so will just about any high tech insulating layer jackets you can buy for 2x the price from a sporting and outdoor store.

This does not get a 5 star rating because it only has one pocket. It would be nice for a garment designed to keep you warm were to have hand-warmer pockets.

Mukavan yksinkertainen takki ja todella lämmin. Aivan loistava käytettynä tuulenpitävän kuoren alla, esim. smock-takki. Peittoaa helposti muut omistamani untuva ja tekokuitu lämpötakkini. Enemmän ajatuksia videolla: https://www.youtube.com/watch?v=cTPqty2tO3g

Great jacket. I live in Finland but work in Norway and that´s a perfect situation to have this kind of thing. Fits anywhere and its super warm. I use it with a gore tex shell on and its perfect for travelling in the cold (I have tried in -5/-10). Downsides, I see loose threads here and there. I hope it doesn´t mean that it won´t last long. But we´ll see.

As almost every one I don´t give more stars because of: 1-just one pocket (quite big though), 2-the threads I see around

AND !!!

3-the lack of "one hand" adjustments. Come on guys, I would pay a little extra for one hand tightener adjustments. That´s a must in any outdoor/military clothes.

UPDATE: Actually the jacket HAS one had adjustments. It can be only mine but they work so bad I tought it didn´t have. The plastic buckle is so tight that I feel I´m gonna break the cloth if I pull so hard so I finally use both hands. But... yeah, ok, it has one hand adjustments.

Honestly, I would invest a bit more and buy the Carinthia model. But if you can´t afford it, this one is a very good piece of cloth.

Great product. Warm and fits perfect under a shelljacket or smock, I would realy appreciate an even warmer option though as this insulation is a bit to little for use when the temperature drops under -10C. Also the jacket would benefit from some type of extra reinforcment as the outer layer zipper most likely will get stuck and tear the fabric If not carefull. All in all a great product though.

Vetoketjut halvan oloiset ja takin kangas on jatkuvasti vetskarin hampaiden välissä. Koko potin kruunasi kun vetskari hajosi muutaman kerran käytön jälkeen kesken Lapin syysvaelluksen normaalisti päälle pukiessa. Kiva. Lisäksi irtonaisia langanpäitä näkyvissä eli se siitä viimeistelystä.

Kesämakuupussissa lisäeristeenä käytettynä osoittautui jostain syystä kylmemmäksi kuin level 2 merinopoolo. Jäin kaipaamaan myös niitä sivutaskuja. Takki osoittautui pettymykseksi ja meni palautukseen, propsit kuitenkin nohevasta toiminnasta vetskarin tuotevirhevastuun osalta.

Hinta monelle houkuttelevampi kuin esim. Carinthian tuotteissa muttei siltikään voita perinteistä brittisoftieta hinta-laatusuhteessa. Ihan ok takki perusperiaatteeltaan, mutta vaativammalle käyttäjälle suosittelisin mielummin Carinthian tai Arc'teryxin lämpötakkeja taikka budjettitietoiselle brittisoftieta.

Oma takkini on osoittautunut kestäväksi ja toimivaksi vaikka onkin ollut ihan sinänsä aktiivisessa käytössä nyt puolisen vuotta -> Tuomas R:n kohdalle lienee osunut se sitruuna =(

Arvostan sitä että lekan suunnittelu- ja toteutusporukka on osannut pitää päänsä kylmänä ja ko. takin käyttötarkoituksen kirkkaana mielessään, ja siksi on _aivan oikea päätös_ että tästä takista on jätetty pois mm.
-velcropaikat tai muut typeryydet

Jokainen edellämainituista ominaisuuksista ennenkaikkea heikentää takin pakattavuutta, mutta myös lisää hintaa ja painoa tuomatta juuri lisäarvoa tilalle.

Parannusehdotuksena kuitenkin sellanen vetoketjun tuulilistan hiukan tukevampi "suojakagas" kuten esim. Carinthian LIGissä on, ehkäisee tehokkaasti kankaan hakeutumisen vetoketjun väliin jota nyt välillä pääsee tapahtumaan.

Tällä hetkellä yksi rakkaimmista vaatekappaleistani meidän valikoimista. Käytännössä aina mukana. On kevyt, pakkautuu pieneen tilaan ja tarjoaa käyttäjälleen lämpimän ja pörröisen olon. Tyylikkään näköinen ihan sellaisenaankin, joten toimii kevyenä toppatakkina sivistyksen parissa. Oikeuksiinsa Särmä TST L3 lämpötakki pääsee metsässä. Toimii taukovaatteena tai sitten kylmemmillä keleillä väliasuna. Särmä TST L3 Lämpötakin, lämpöhousujen ja Särmä TST lämpöviitan yhdistelmällä vetelee sikeitä varsin kylmillä keleillä ilman ongelmia. Itselläni tämä on aina kertausharjoituksissa mukana ja menee oikein hyvin esimerkiksi chestrigin yleistaskuun, josta vilun iskiessä takki on nopea riipaista päälle.

At this point, Särmä TST L3 Loft Jacket is the dearest piece of garment we have in the assortment for me, and it is an integral part of my EDC kit. The jacket is lightweight, packs into small space and offers a warm and fluffy feeling for the user. Looks pretty smart on its own so works well as a lightweight loft jacket even in an urban environment. In a woods, Särmä TST L3 Loft Jacket truly shows its performance. Works well as an extra layer during breaks and as a mid-layer during the colder weather. Combining Särmä TST L3 Loft Jacket, trousers and Särmä TST Thermal cloak I have slept well in quite cold conditions. Every time I go into military exercises, I carry loft jacket in my webbing. Jacket fits nicely in general purpose pouch, where it can be easily accessed when needed.

I purchased the olive green version, sized XL. At the price, this is an excellent product, fit for its intended purpose as a thermal layer under an outer shell, but over a base layer and some personal equipment / vest, etc. I deducted one star because of its single pocket, which makes it difficult to utilize on its own (over a base layer), and also for the somewhat delicate zipper - which I suspect will sooner or later snag in the material and possibly rip it. I will use it as suggested in the product description - including as a thermal pajama top within a Carinthia sleeping bag (Finnish M05 / Defence 4, Defence 1, or maybe a Jerven Fjelldukken King sized or Executive (with extreme cold weather liner). I will likely also acquire the matching pants, as well as maybe an XXL version to wear over my heavier work kit. I was considering the Carinthia product, but the Sarma version is less than half the price, and from what I can tell, offers about the same thermal qualities. PLEASE clarify the washing instructions somewhere in your product description. I am looking forward to a cold Canadian winter so I can take this ice fishing and on expeditions.

Vetoketju kaipaa tuulilistaa. Ihan ok muuten, mutta esim hollantilainen pakkastakki on halvempi ja toimivampi.

1. This jacket really needs some more pockets and I would gladly pay extra for more pockets.

2. The zippers are ok but nothing special and not double row stitch.

*******(UPDATE 11/15) upgrade to 3.5 stars
I wore this jacket a bit in moderately cold weather on the range and woods in mid 20's F. with only T shirt under. The insulation is good and never felt cold. and its stopped wind very well. It is warmer than my previous comperable jacket that uses primaloft insulation.

As long as you dont need large pockets I would now recommend this jacket. It would make good insulation layer under a hardshell.

******(update 12/4) downgrade back to 2.5 stars
After two hunting trips with one near 0'F in Maine the insulation is good but lack of pockets very annoying.
The zippers are SHIT. they are already hanging and getting sticky. Real outdoor gear use #8 to #10 zippers not this cheap crap. And why are the zippers set like female clothing on the opposite side.
Ive already ordered a wild thingsgear jacket like the one I used in the Military to replace this jacket.

Pro's: warm insulation jacket. Used it during cold days / nights under other jackets (most extreme: 0 degrees, winds around 5 BFT, open water and no shelter: still warm). When not needed, it can also be stored quite easily in a pack.

Con's: material is not velcro friendly. I have a pair of Mechanix gloves with velcro closure which damaged both cuffs significant over 2 days. The main zipper is also a concern, you don't want to be in a rush :-). Sometimes it's sticky and make sure it doesn't get stuck on the fabric.

I like this piece of gear for many reasons: 1. the price, very reasonable. 2. the value 3. it works well 4. it's very lite and extremely compact. I use this jacket in my call out gear for the "Search and rescue" team I'm a member of here in the states (Arizona). We conduct operations in the desert, the mountains, the Grand canyon and lakes as well as rivers. This jacket stays in my 2 day pack, that I deploy with on rescue and recovery operations. Because of the amount of gear we carry, this fits in very well and only taking up minimum space in my ruck allowing me to load other items. It is extremely comfortable, warm and useful. Its also an excellent addition to a layer system, I routinely put my gortex jacket hard shell over it and I can easily stay warm in sub-zero temps. I highly recommend this product.

This is a serviceable jacket, especially if it’s going to be used as a liner under a shell garment. The zipper is adequate for the task and the double sliders allow a short fella like me to unzip a bit from the bottom of the jacket to sit comfortably.
Two suggestions for the next version: a means to attach a hood (I dislike built-in hoods), and a small rectangular stuff sack to allow this jacket to be used as a pillow.
For folks who want a slightly tougher jacket with two pockets and a beefier zipper, take a look at Wiggy’s Sweater with Lamilite insulation (old name for Climashield).

This is a VERY good liner. It works great under a smock, field jacket, or hard shell. It can also work under a blouse if the collar is acceptable, it's the collar that makes this so much better than many other liners. It is extremely vapor permeable. The cuffs work well and the asymmetrical hem drawcord works great when carrying a pistol. It's a little fragile for a standalone outer garment, but it will do OK in a benign environment. I took it on a late season snowshoeing trip, above 3,500 m, freezing in the daytime and about -15 C at night. It worked perfectly under a 40 D Vertex smock, vented very well going uphill and dried before I stopped. I'm still trying to figure out the temperature range. First impressions are that it will add 10-20 C to whatever you are wearing, maybe more. I like it enough that I'm getting a few more to put in our go bags.

Update: I did get a second one and I was surprised by the differences between the gray and green versions. The gray version has a better double slider zipper allowing you to vent the bottom of the jacket. It seems a somewhat better/stronger zipper too. The green version has a semetrical hem drawcord, but the adjustments are well placed at the front. I might rate the green version 4.5 stars that zipper might get replaced.

Lightweight, comfortable, warm and thin enough to be worn under a regular jacket, above a heavyweight base-layer. I wasn't a big fan of the German Bundeswehr cold-weather quilted (under-)pants and jacket (Liner) back then, but this jacket (and the pants) are great. They keep you warm and are not bulky at all. They are soft and not as stiff as other thermal mid-layers. Highly recommended.
The complaint about the zippers is understandable. The zippers are really small and maybe not the best choice, but they work so far.
The other complains here about the zipper being on the "wrong" side (female-zippers in the US) is definitely not a real issue. All zippers in Europe are made this way and that's something to get used to very easy (like the metric-system).

Should start by saying this is my favorite piece of gear I've ever bought from Varusteleka.

Warm and puffy, packs down nice. Elastic cord locks on the hem and elastic bands for the wrists are a must-have to keep the cold out. Sometimes I wear this jacket even when it's 50 degrees F (not cold really and not something you need a puffy jacket for) just because it's so comfortable.

I see other reviewers taking away stars because they say the jacket only has one pocket... but I don't understand this because Varusteleka tells you that right from the start on the product info section. If they tell you there's only one pocket and you decide to buy it anyway, it's not fair to them to take stars off your review.

Anyway, if I had a complaint, it's the damn main zipper. Feels very low quality, catches and gets stuff often. I feel it will completely fail one day then I'll be left with a jacket that can't zip, making it useless. To the folks at Varusteleka: let's see an updated model with some Kroko or YKK zippers, at least for the main zip!
