This is my first post here. although I am a daily user of Bushcraft USA for the last 8 years. The term Carinthia gets no response here as I believe it is only in Europe. Please bare with me also as I have to run metric measures through a conversion chart.. Also I have scanned through your forum posts on sleeping bags without success to my question. The US military sleep systems is a lot of wieght, and I don't need the extreme temp rating they have. I am in the Tennessee blue ridge mountains, and it only gets down seldom below 13 degrees F. Anyway, I have no knowledge of the term Carinthia, but like a couple of their products I have seen. the Defence 4 bag looks good to me, but the Finnish MO5 looks a lot better as it appears to have a little more room for movement. They seem to both have about the same rating as far as temp. Any comments or advise would be greatly appreciated, I believe medium bag would fit as I am only 5 ft. 9 in, tall, sorry, don't know what that is in metric. Also the company that ships to the US, is Varusteleka, Is this a reputable company. sending money over seas scares me a little. Thank You
