Bird Mountain™ III Insulated Jacket W

A must-have for the mountain, this performance jacket is made with our warmest, most advanced thermal-reflective lining, along with 100% recycled polyester insulation and tons of slope-ready features. Inspired by NASA space blankets, our Omni-Heat™ thermal-reflective technology has been keeping outdoor explorers warm for years. In 2024, our Omni-Heat™ Infinity was even tested on the Moon! But it’s still the same tech we use to keep you comfortable here on earth.
