Women’s WarmCube® Active Aerothermal PrimaLoft® Insulated Vest (Fall 2025)

Lock in on your next alpine adventure in the WarmCube® Active Aerothermal Vest. It’s built to breathe when you’re going hard on the trail or in any cold climate, and to warm you up when you pause to catch your breath. This mountain-ready, thermoregulating vest features zones of 700-fill down cubes with a clever 3D WarmCube® construction that prevents down shift and traps heat in the surrounding air channels to deliver warmth and breathability without weight. PrimaLoft® Active Evolve insulation delivers the perfect mix of breathable warmth and mobility during stop-and-go pursuits. Wear it over a light fleece for a frosty trail run, or use it as a versatile layering piece for ski touring. The down is treated with Down Defender, and the shell is treated with a C0 DWR for an extra level of moisture protection.
