The temptation with down jackets is get the warmest one you’ll be able to. Should you’re spending the winter in northern Wisconsin as I did whereas testing these, that is not a foul concept. However for those who’re simply in search of somewhat additional heat throughout shoulder season journeys, and even excessive altitude summer season backpacking, you do not want an 800 fill energy, massively overstuffed winter parka.
We do counsel sticking with jackets which have a down fill energy score of at the least 500 for mild use, however there is no purpose to spend on a jacket with 900 fill energy down until you are going to be out in beneath freezing temps (otherwise you’re a perpetually chilly particular person). Should you primarily spend your time in much less excessive climates, get a lighter jacket.
Additionally do not forget that, within the case of backpacking you’ll need to bear in mind how packable a jacket is and the way a lot weight it provides to your pack. Sadly, the lightest jackets do are typically greater fill energy, since you’ll be able to lure extra heat with much less down, however once more, be practical in regards to the temperatures you are going to be in and you may get away with a less expensive jacket.
