domex micro rating

hey evryone. I ended up with a Domex micro 2000 sleeping bag lately. i am considering taking it out next weekend but would be nice to know the rating.
definitely not a 4 seasons bag. Nothing on the bag or stuff sack, and I cannot find anything online.
i could go with the bigger Kathmandu one I have but trying to save on room and weight.
worst case I take in the fleece bag liner, which i was contemplating anyway.
We might be in a hut, but at this time of yea,r we might not be the only ones there either, so we could be outside.
Honestly, I don't know the rating on the Kathmandu jobbie, but its a more substantial bag.
