Can anyone id my sleeping bag? (so I know it's rating)

DWR and damp resitant down will only get you so far - so its fine in a sleeping bag when it gets a bit of rain or snow on it, and again, my Mountain Equipment Lightline has Drilite fabric, which water resistant (I got caught in rain wearing it, and yes, it beaded pretty well). but my Arete has Heiium, which is not. But I wouldnt wear either in the rain. Which is the same with Rab - the Pertex Quantum range has DWR, but its not fair to call it waterproof. Even synthetic would struggle.
