It is the best bag they have made imo and Ive tried many. This has much more down than a helium and only weights 4 oz more. The girth at the shoulder is 64 inches which is nice and wide, can be layered with parkas or even another lighter bag in deep winter conditions.The shell has a water proof coating. The seams are not taped.
But against rent wall condensation or even snow caves you are good. Foot box has twice the loft as the rest of the bag. Awesome feature that keeps your feet warm in winter.
So it is warmer than the helium. I just washed this with grangers today do its nice and clean and lofty. 800 fill goose down not duck down. Treated with Nike ax down proof. I never used the liner but it always rode in the stuffsack with the bag.
These are MADE BETTER than any marmot big Agnes or Nemo product out today. Everyone is using duck down now and nobody has a foot box or warm hood like this bag.Cant find the stuff sack for the bag or liner. Id recommend a sea to summit compression sack anyway to take advantage of the 800 fill down. But if you know sleeping bags you already know about this one for winter.
