Rab Mythic Ultra sleeping bags 

If you need anyone to do a field test on this great looking bag... I was out in -12 a few weeks ago , in the north of england. So I would have liked to see lower temps on the unit.. I currently use the ascent 1100 . I match it with your 5.5 sleep mat.. very warm but very bulky, takes up so much of my bag... great quality though. Thanks Rab .. edit ok just seen your video on the mythic ultra 600 that goes down to -12.. that's the one for me...
