The ultralight Western Mountaineering Flash down pants provide ample warmth for high-altitude summer backpacking trips, fast-and light mountaineering, or active winter use. They easily slide under a shell in wet conditions. Designed to provide more warmth than a thick pair of fleece bottoms, the Flash Pants offer less weight and a substantially smaller packed size than any synthetic alternative. The average weight for a pair of these pants is roughly 180 grams and they'll compress down to about half the size of your water bottle. What a great way to lighten your pack and raise your comfort level on your next trip!

Western Mountaineering's top-notch construction methods, attention to detail, and years of experience working solely with premium down set them apart from other brands; they are simply one of the world's best down companies, bar none. Based in San Jose, CA, they are committed to manufacturing the in USA. Their down is sourced from free-range mother geese who are never live-plucked or force-fed.
