I just got mine, no chance to test yet. I think I may have spent some time in a exhaust filled truck (stank of petrol fumes). I was also a bit concerned that there was no markings anywhere of model, and the loft felt a bit small for a serious 3-season bag. Anyone with one who can measure theirs and compare?
The design appears to be ok, I like centre zip (I have a Carinthia Survival One for true winter use), the draft collar appears to perhaps be a bit too low down for me, time will tell. It is not a large bag, so I suspect that large size people might not fit well in it.
I'll try to get a chance to try it out this weekend, temps should be around 0C, perhaps a bit less at night.
