Advanced global traceable down feathers are certified by NSF International. The feathers are able to be tracked from start to finish, with the treatment of the birds meeting strict guidelines to ensure humane treatment to make sure the birds are not force-fed nor live-plucked. Yes, these horrors do still occur in this day and age, but you do not have to be a part of it or fund it. Look for this certification on any puffer jacket you buy if you support this cause.
