The men's HyBridge Lite Vest is a premium insulator built for light warmth and fitted crisp weather performance. It's padded with 800 fill goose down for warmth. Thermal Mapping technology strategically places more insulation where it's most needed. Quilt-through construction reduces its pack size and improves your layering capabilities. Tensile-Tech hardface side panels provide an athletic fit, flexibility, and breathability. An insulated collar with a brushed tricot lining seals in core warmth.
