The HyperDown collection was engineered with low temperatures and high altitudes in mind. The cutting-edge insulation is constructed to combat the frigid temperatures and blistering winds of late-season hunts. Blending the warmth-to-weight superiority of down and the compression-resistant performance of synthetic insulation creates the ultimate lightweight defense against wintry conditions. The top-tier warmth is wrapped in a durable ripstop face fabric for further protection on hunts that call harsh environments home.

This is the warmest puffer jacket we make, built to be light and packable for the ounce-counting big-game hunter on their coldest hunts. Made with 800-fill PrimaLoft® Gold down blend, the insulation resists clumping in wet conditions maintaining warmth when you need it most. A 27D ripstop face fabric makes the HyperDown Jacket as tough as the conditions it is worn in, and it is cut to fit over your other layers and optics harness for rapid deployment.
