Temptation with descending jackets is to obtain the warmest you can. If you spend the winter in northern Wisconsin as I did while I tried these, that is not a bad idea. But if you are only looking for a little more extra extra during the trips of the shoulder season, or even the summer backpack of great altitude, it does not need a stuffing power of 800, greatly overloaded winter parka.
We suggest staying with jackets that have a classification of filling energy down at least 500 for light use, but there is no reason to spend a jacket with 900 ignition filling unless it comes to freezing temperatures below (or you ‘re a perpetually cold person). If you mainly spend your time in less extreme climates, get a lighter jacket.
Also remember that, in the case of backpackers, you will want to take into account how supportable it is a jacket and how much weight adds to your package. Unfortunately, the lighter jackets tend to be a higher filling power, since you can catch more warmth with less below, but again, be realistic about the temperatures in which you are going to be and you can get out with a cheaper jacket .
