Choose a hiking down jacket by multiplying fill power by the amount of down, not by fill power alone. No. 1 is the NANGA Aurora Tex Light Mikami, with 180g of 860FP down and a loft of about 84.6L by my calculation. I lined up six jackets by the down weight, FP and price on NANGA's pages, and worked out the price per liter too.Ranking · Oct 17, 2026
