Flash Vest – Ultralight Down Vest

The Flash Vest is an ultralight down vest that delivers reliable core warmth without tipping the scale. Weighing just 5 oz (140g), this minimalist layer is ideal for gram-counters, thru-hikers, alpine climbers, and trail runners looking to extend their comfort window without sacrificing speed.

Filled with 850+ fill power ethically sourced goose down, the Flash Vest offers remarkable warmth for its weight. The full-length zipper makes it easy to layer or vent on the go, while reflective trim boosts low-light visibility for early starts or late descents. Its highly compressible design stashes easily into any pack pocket or stuff sack, making it a perfect just-in-case insulation piece for ultralight missions.

Despite its featherweight status, the Flash Vest is built for real-world performance — keeping your core warm during alpine rest stops, early morning treks, or exposed ridge traverses. Whether you’re pushing through a thru-hike or shaving ounces on your next summit push, the Flash Vest delivers dependable warmth when it counts.
