I use it last couple of months(April-June) as a separate parts(not cold enough to test it complete). I test the outer part on rain and bike and it is waterproof. I experience greenhouse effect, but I guess the problem is in my body. I find 10cm zips under the arm a good idea and use the jacke with those zips open for better ventilation. The hat is not as well made as my old Lafuma and do not stay stable. I would prefer if it could be packed in the collar. The pockets are well placed and the zips are OK. I find strange that man jacke use left zip as for ladies. The outer part is a bit longer than the inner(well seen at the pictures posted), which could be for better rain protection. The way inner and outer parts are connected is not the most robust I've seen.
I would recommend it for active persons as everyday jacke
