All my bags are down as well. I have a -20 degree REI bag that I bought back in 1974. I've washed it multiple times and it still is going strong. Even though I live in a rainy climate and hike a lot in the rain I've always managed to keep my down bags dry by packing them in a plastic bag within my pack. I've never gotten one wet, though they have gotten damp from condensation within a tent. Western Mountaineering is the top brand of sleeping bag on the market. It is the most expensive but the best quality.
