The Micro Puff® Jacket is your secret weapon against the cold — featherlight, fiercely warm, and built for whatever wild, messy weather you find yourself in. Crafted from ultralight Pertex® Quantum shell fabric and packed with revolutionary PlumaFill insulation, it delivers the best warmth-to-weight ratio we’ve ever made and packs down smaller than any of our synthetic jackets. The shell? NetPlus® 100% postconsumer recycled nylon ripstop made from discarded fishing nets. The insulation? 100% recycled polyester. Responsibly made in a Fair Trade Certified™ factory. When conditions get cold, wet, and unpredictable — this is the jacket you want in your corner.
