I am looking to get a down jacket and would like a jacket that would keep me warm winter camping in subzero temperatures. I hike all winter season and want to be prepared when it gets really cold. Do you have any suggestions on a jacket and on the fill? I know Mountain Hardware has hooded down jacket that is 650 fill. Will 650 fill be adequate in the whites in middle of winter or should I get a 750 or 850 fill?
Thanks
The difference between 550, 650, 750 and 850 down has nothing to do with warmth.
The key thing to look for in down jackets and bags is
loft. A 550 parka with 6" of loft and an 850 parka with 6" of loft will keep you just as warm. The only difference s are that the 850 parka will a) weigh a few grams less and b) be more expensive by many dollars. The law of diminishing returns applies. More deeply, the numeric values on the down plays into a standard marketing game of "more is better" that is almost impossible for consumers to resist.
IMO, there are 2 basic style of down jackets that make sense. The first is the down sweater. These are waist length, are almost always quilted (sticthed through) and are nice ways to carry a lot of warmth in a little bit of pack room. In general, they get worn
under a shell. But truth be told, I use mine more for around town wear than real winter bc use.
The second and much more useful style of jacket is the belay parka style. These are hip length jackets and are generally baffeled (the stitching doesn't go all the way through) like a sleeping bag to provide more loft. They are sized big so that you can wear them [b[over[/b] your shell at rest stops. By far, this is my favorite type of jacket for New England winters. I keep mine near the top of my pack and it comes out at rest stops and in camp.
Actually, I've been carrying a Marmont Primaloft Belay Jacket for many years and like it well enough. The Patagonia DAS Parka is another nice one. There are loads of down belay parkas out there too and if I had the coin, I would move to down for the bettter weight and packability.
Some of the features that I would insist on are:
+ Permenantly attached hood
+ Baffled construction
+ Waterresistant outer shell
+ Longer hip length
+ 4 outer pockets
I'm sure that Marmot, Patagonia, TNF, Mountain Hardware and EMS all make jackets like this. Names change frequently.
