Western Mountaineering Flash Vest

The Western Mountaineering Flash Vest is an ultralight down vest that adds core warmth for hiking, climbing and trail running. It weighs about 5 oz and is filled with 850+ fill power goose down under a 20-denier ripstop shell. A full-length YKK zipper makes it easy to vent or layer, and reflective trim helps with visibility in low light. It compresses small enough to stash in a pack pocket as a just-in-case warm layer. Western Mountaineering states it is "Made in the USA."
