Built for three-season backpacking in the kind of unpredictable weather we see across the Southeast, the Greystone 20 is our pick for campers who don't want to coddle their gear. DownTek-treated 650-fill down resists moisture and holds its loft when humidity or a surprise shower rolls in, keeping you warm down to 20°F without the extra weight of synthetic fill.
