Great investment
Have only had the sleeping bag for a short while and used it on one occasion. It is brilliant and really does everything as promised giving me four nights of really refreshing sleep keeping me very comfortable The service provided by the company is first class and they present as very committed to ensuring you are supported and advised appropriately. I am really looking forward to using my bag again knowing I will be warm dry and have a refreshing nights sleep which will ensure I get the best from my trips

Very toasty at 0°C
The quality of the bag is excellent. I tried it out last night in temperatures 🌡 at 0°C. I was very toasty. If anything I got too warm. I highly recommend this.

Super sleeping bag - review after >1yr of use!
I slept in this during the week for 14months straight. I was in a small tent in the UK. I experienced snow, rain, winds and a balmy summer - typical of English weather. The bag performed really very well - I was always warm enough and had some of the best sleeps of my life. It did get wet/damp a couple of times but easily dried out. Zip always worked fine. Not one fault.

Too small/tight.
Haven't tested it in any real conditions. Just size tested at home and found it too small. The bag seems otherwise well priced for what it is claiming to offer. Really is lightweight. Does loft up nicely if left open and out for 30m. Make sure to store at home by hanging up or in a much larger mesh lining bag and not in the compression sack. Zipper works great and didn't feel cheap at all. Compresses quite small. It has a cinch system for tightening around your neck and another one for tightening around your face. This is v important for cold temperatures. But the outer material of the bag didn't feel durable and I guess the excuse here would be that it was a feature to reduce weight. I am 5"10 120kg so this was definitely too small for me. I was stretching it out at the top and the bottom and I didn't know how long the seams would last with me doing that. A sleeping bag should give many years of life. I could give it less than 4 stars. Definitely not 5.

Nice piece of kit
Haven't used it yet apart from checking I fit in it, I'm 6'2" and the large bag has more room than many other I've had. Repacking into the stuff sack is awkward I'll need a few practices before I try this out on a mountain side. Can't fault it for quality. I'll update in a few weeks if I get a chance to escape the city for a few nights. ** quick update, first use went well the sleeping bag is perfect for me. I've thrown the stuff sac/compression bag in the bin. it takes way too long to get it in there I've substituted a large lightweight dry bag for it. dry bag takes 30 seconds to fill, another 30 seconds to get all the air out and it packs smaller than the compression bag.

Would be better with taped seems
Plenty warm , and a fair price , but stitching at feet end starting to fail , used stick on patches to fix . Expected better . Might just be a one off flaw . I can live with it.

Sac reçu en 48h (merci Amazon prime). Il est vraiment parfait. Hyper chaud et de bonne facture. C’est impressionnant de voir comme il se gonfle quand on le déplie. Je viens d’un sac de couchage Decathlon vieux de 15ans. Ceci est clairement un upgrade. On bivouaque sous tente et dans un campervan par températures automnales /printanières. Mon enfant avait trop chaud. Enfin, j’ai bien aimé la philosophie de la société et c’est ça aussi qui m’a décidé à prendre ce modèle. En plus ils sont garantis à vie ! N’hésitez pas. Vous ne serez pas déçus.

Here's the package we bought below. We wanted to get lightweight, compressible gear (for backpacking in mountains for days), that's easy to set up, comfortable, and warm. Ever since we first tried this package out together, we were sold on it, and have used it ever since (January, February, March '21 backpackers this year). And I anticipate using it for a very long time going forward. We used this package on the Appalachian Trail and Rocky Mountains backpacking in single degree weather, and we were as warm being in our own house. No joke. We could not believe how warm and comfortable we were. It would even get hot at times (we had thermal top and bottoms on only) so we had to peek our head out a little to get some cool air. And comfort? So comfortable. We (my 15, 16, 19 yr old boys and I) are never going back to tent camping ever. This is too good. So easy too. No worries about wetness on the ground, rain hitting the tent, packing up a wet tent, sleeping on the hard ground (we even had super killer self-inflating camping pads are that are awesome, but it's still a degree of hardness because you're on DIRT!), mildew worries from tent moisture, etc. etc. The time it takes to set up and take down is incredible. Obviously, you need trees or some other structure to hook onto. But other than that, this is the way to go for us. Best of luck with finding your ideal set up. We found ours.

Gute Qualität bequem und wärmt

Lo probé la semana pasada en unas condiciones intermedias, use una tienda de campaña y la temperatura dentro era de 2 grados! Además fuera hacía un viento bastante fuerte que aumentaba la sensación de frió y aunque tengo una buena tienda el saco lógicamente era necesario. El resultado fue excelente, dormí en calzoncillos y una camiseta térmica y no pase nada de frío. Ni siquiera necesite cerrarlo por completo porque el calor que conservaba era mas que suficiente! En teoría tiene una temperatura de confort de -10ªC y la verdad es que es bastante factible que a esa temperatura no pases ni gota de frío. Por mi parte muy contento de haber acertado, además al ser negro es discreto, detalle que a mí me gusta al llevarlo atado a la mochila!
