One jacket, three ways to wear it. The versatile Columbia® Amaze Puff Interchange Jacket is a 3-in-1 design jacket that combines a waterproof-breathable shell with a separate down puffer, giving you the flexibility to adapt as conditions change. Wear either layer alone or together for added warmth, while adjustable drawcord hems help seal in comfort. Featuring Omni-Tech™ waterproof-breathable technology with fully seam-sealed construction that helps keep moisture from seeping through the seams.
