The temptation with down jackets is get the warmest one you possibly can. If you happen to’re spending the winter in northern Wisconsin as I did whereas testing these, that is not a nasty concept. However in case you’re simply searching for slightly further 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 power rating of at the very least 500 for gentle use, however there isn’t any motive to spend on a jacket with 900 fill energy down except you are going to be out in beneath freezing temps (otherwise you’re a perpetually cold person). If you happen to 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 remember how packable a jacket is and the way a lot weight it provides to your pack. Sadly, the lightest jackets do are usually increased fill energy, since you possibly can 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.
