Now a short review about the Bundeswehr (german army) bivy made by Carinthia which can be bought for 100€, which is cheap when you compare it to other bivys made by Carinthia. I tested this model for some time, under different circumstances, even under rain and I can honestly say that this one is waterproof. So I am very satisfied with this model, and because of that I thought I could make a review to show this bivy to you and so maybe help someone in his decision whether or not to buy this one. So stick with me when you want to know more about this bivouac sack. I bought this model for 100€ at ASMC and it is difficult to buy one because there is a high demand. It was declared as used, but was in mint condition when I got it. It has some handwritten marks, so I guess it was in possession by the Bundeswehr but never in use. Some facts: at the top it is approx. 85cm wide, at the bottom it is approx. 65cm; length is approx. 200cm This is, in my opinion, one advantage of this bivy, because there is plenty of room inside. You have the possibility to put your sleeping mat, equipment and yourself at once into this sack and still have some room left. Once I had my 40L rucksack laying in the last third with my legs, my boots placed somewhere in the middle and I had no problems to close the bivy an turn myself around in the night. This means you can just put this bivouac bag in your rucksack and have the possibility to protect your hole gear against the rain when worst comes to worst. Another great advantage is the Gore-Text Best Defense material which is much more robust than the Gore-Tex material used for for example jackets. Because of this, there is no need to protect the bivy itself against the ground and you can lay the bivy directly on normal forest floor. If you intend to sleep on rocky ground it might be better to lay a protective layer between the ground and the bivy. But my personal overall impression of the Gore-Text Best Defense is, that it is very robust and plays along well. The biggest advantage is also linked with the Gore-Tex material. In a bivy you can have a problem with moisture, if the sack is not breathable. This depends on the material as well as the incline in temperature between the innards of the bivy and the surrounding air. But this one is breathable (!) and I had no problems with moisture (air humidity) in the bivy, even in higher temperatures (up to 15°C). Above that I was not able to test it so far. So for me this is the first one with which I had no problems with moisture so far and this an absolute plus. What you can do, when it is not raining, is to close just the velcro and leave the zipper unzipped. In this case you have much more vent for the air humidity to escape. What else is there to say. Not much more… The seams are all laminated and so, I have not said it so far, this bivouac sack is also water-repellent. I slept some nights under rain with this bivy and was still dry in the morning and so it fits for its purpose. As far as I can judge it, Carinthia is a producer known not to produce just some stuff but good and reliable products. This much to the Bundeswehr (german army) bivouac sack by Carinthia. As you could see and hear (or read) I am very satisfied with this model and can honestly recommend it, if someone of you guys plans to buy a new bivy. If you have further questions you can write a comment and I will answer as soon as possible. Thanks for watching and have a good time in the bush!
