but my point is; if you’re not carrying it up a mountain, you don’t need the lightweight-ness of down.
down jackets cost more than synthetics.
they’re more delicate – no point wrapping all that light down in a heavy rugged jacket.
you can buy synthetic jackets that are just as warm, they’ll be a bit heavier, but cheaper and less sensitive to care.
down jackets/sleeping bags shouldn’t be stored compressed – cos you’ll knacker the feathers, you need to store them hanging, exposed to the air. (don’t store your £200 down s’bag in it’s stuff-sack)
Down is great stuff, but it’s not perfect. Synthetics offer more for less for almost everyone, and they’re warm when they’re wet.
if you’ve got a down jacket and you like it, then great. keep it and use it. preserve our resources, etc. but don’t think that a warm jacket has to be down, it probably does if you want to take it up K2, but for everyone else there’s the cheaper option of a more robust synthetic jacket that will be warmer in the rain that you’re more likely to see on a hill in Britain.
