The Defence 4 may be Carinthia's best all-around sleeping bag. Designed for cold and nasty weather, it's no surprise that (among others) also the Finnish army adopted this very model! This here is a reliable choice, designed for very demanding use!

  • Three season bag with comfort rating as low as -15°C / 5°F
  • Weight about two kilograms / a bit over four pounds
  • Military-grade materials

The Defence sleeping bag series is designed for military use, the materials and overall properties are all made with that in mind.

Comes with a compression bag, which is compressional both height and lengthwise.

Bag model

  • The mummy shape: Here, the criteria of stuff size, weight, and warmth are most important. The tapered foot section reduces weight and stuff size. The main advantage is, however, that from the knee downwards, there is increasingly less internal volume to keep warm. The foot section should not be so small that the feet cause the layers of insulation to poke out. A trapezoidal foot section has proven to be ideal. A wedge shape, declining evenly in width from top to bottom, does not fit the true proportions of the body.
  • Two-way zipper: All Carinthia military sleeping bags are equipped with a two-way zipper. The glider on the top does not snag, allowing a quick step out if necessary (in case of alert for example). The glider below does stick and can be opened for ventilation.
  • Trapezoidal foot section: Experience has shown that the trapezoidal cut provides the ultimate foot space. In a normal sleeping position, the feet do not poke the insulation outward, avoiding cold spots. There is also enough room to store a shoe bag or extra clothing.
  • The outer shell fits loosely over the bag innards, providing an extra insulating layer of air. This also eliminates heat loss due to seams combining the shell with the fillings. Overall this feature enhances the bag's performance considerably!


  • Shellproof outer shell - a lightweight, hard-wearing, ripstop reinforced and specially treated polyamide which is both wind and waterproof (1000 mm), yet breathable.
  • Shelltrans lining - a soft to the skin ripstop reinforced polyamide with excellent moisture-wicking capabilities keeps you comfortable through the night.
  • Thermoflect, a very thin, very lightweight aluminium material which reflects body heat. Thermoflect raises the sleeping bags heat-retaining capacity by about 11 %.
  • G-Loft filling - Carinthias own, in-house "hollow-fibre", made in Austria. Highly compressible, excellent weight-insulation ratio, and also moisture resistant, meaning that it will work even under long term use in damp conditions.
  • Defence 4 uses double layered G-Loft filling. Two G-LOFT Plus insulation layers are arranged in such a way that the quilting is offset. The shell is attached afterwards, creating a further layer of air between the quilted insulation and the shell. With no stitch perforations in the shell, it is fairly water-resistant and free of unintended ventilation.

Carinthia sleeping bags are not entirely PFC-free, but do have the Oeko-Tex certificate, Standard 100.


Temperature specification

Comfort represents enjoyable-to-sleep temperature while Extreme is the rating where an average-sized male will survive through the night, so go for Comfort when choosing a suitable sleeping bag.

  • Comfort: -8.8°C to -15° C / 47.8°F to 5°F
  • Extreme: -38°C / -36.4°F

Hinta/(lämpö * paino) -suhteelta hyvä pussi. On kyllä todella tilava ja mukava. Ainoa isompi miinus siitä, ettei pussissa ole hartioiden päälle kiristettävää lämpösulkua.

Kelpo makuupussi ja ykkösen kanssa sopiva kovemmassa pakkasessa. Itsellä toimii, kun sujauttaa leveän kuminauhan pään ja pussin ympärille, lämpösulku on siinä ja suuaukko pysyy mukavammin oikeassa kohdassa. Esim joittenkin makuualustojen ympäriltä löytyy sopiva kuminauha.

I've used Defence 4 bags for 15 years, got my third one now. I've occasionnaly used several high end mountaineering down bags, and rugged Wiggys bag, but for me nothing beats the Def 4 for safety and comfort when sleeping rough. It is perfectly windproof, drastically reducing the need for a proper shelter. And it is water resistant enough for you not to care about rain or melting snow. This thing is just perfect in a snow hole as well as on the side of a bare mountain. The zip never catches and never fails. The absence of a collar helps for quick operation and is not an issue in practice. I can't imagine myself taking responsibility for a group at night in tough weather and using anything else than the trusty Def 4 for me to return to.

Muuten todella hyvä mutta vetoketju aukeaa helposti vahingossa. Vähänkään mönkii niin on yhtäkkiä vyötäröä myöten auki. Ärsyttävä ominaisuus mutta ehkä korjattavissa pienellä neppari modauksella...

Had the Defence 4 a long time ago and tried many other sleeping bags since then and finally came back to this. It is not the lightest, smallest or warmest sleeping bag you can buy, but a tough, durable, reliable and extremely well build one. No wonder many militaries use these as there standard sleeping bag (that's where I know it from). It's made for use and abuse in the field and it won't disappoint. As a male you are good down to -10 to -15 degrees C with this and still get a good night of sleep.

Ensinnäkin toimitus oli nopea, kiitos siitä. Makuupussi oli juuri sitä mitä odotettiin. Makuupussissa oli sopiva lämmin nukkua yön yli metsässä. Vaatetuksena pussin sisällä oli college-housut, puuvillasekoitesukat ja huokoinen villapaita. Alussa päässä oli pipo mutta pipo päässä tuli liian kuuma ja sen käytöstä luovuin. Pakkanen vaihteli -6 ja -8 asteen välillä. Makuualustana toimi havunoksat ja ihan perus telttapatja.

Pussin kosteudenpoisto toimi myös. Pussin sisällä ei ollut havaittavaa kosteutta. Aamulla pussin ulkopintaan oli kertynyt hieman kosteutta mutta se on ihan normaalia.

Makuupussin laadun näkee ja tuntee. Pussi pakkautuu vaivattomasti kompressiopussiin.

Luonnollisesti metsäreissuilla savun tuoksu tarttuu varusteisiin mutta makuupussista savun tuoksu hävisi muutaman päivän tuuletuksen jälkeen.

Suosittelen kyseistä tuotetta. Hinta-laatusuhde on erinomainen.Ostaja ei tätä arvostelua kirjoittanut. Kirjoittajana toimi ostajan puoliso(mies).

i ordered a different sleeping bag before and it was made of thin material. and it was gigantic for a 0 degree F bag. THIS ONE i ordered is the best all around heavy duty sleeping bag for cold weather i have ever used, i used it at about 25°F or about -4°C i want to say? i may be wrong but it kept me dry and warm. the hood is big enough to put a small pillow inside behind your head. i really like it and doesnt take up too much space in your pack like other synthetic insulation sleeping bags. it is the best all around one ive used i know it will never fail me. the zipper and the stitching is good. i had a coleman before and the stitching came apart on me. i had a thermarest cenrauri sleeping bag for similar temperature and it felt like it was made of dead skin from being sunburned and my cat easily popped a hole and tore the thing and i returned that shit. the carinthia feels bomb proof. For a survival sleeping bag that will never die go with carinthia defense 4 you wont regret the buy.
