The highly packable Micro Puff Jacket is Patagonia's go-to insulation piece for mixed cold conditions. It combines ultralight Pertex Quantum shell fabric with PlumaFill insulation to deliver the best warmth-to-weight ratio and the highest compressibility of Patagonia's synthetic jackets. This means the Micro Puff is the perfect warm layer to pack when you're expecting temps to drop. A PFC-free durable water-repellent (DWR) finish sheds light precipitation while elasticized cuffs and an adjustable hem help seal in warmth. To sweeten the deal, the Micro Puff is a sustainable insulation option. Its Pertex Quantum shell fabric is made of NetPlus 100% recycled fishing nets, which helps reduce ocean plastic pollution, and the PlumaFill is made from recycled polyester. Be ready for any conditions with the Patagonia Micro Puff Jacket on hand. Pertex Quantum shell blocks the wind to preserve warmth Lightweight PlumaFill insulation offers the warmth and packability of down with the warm-when-wet performance of synthetic Innovative quilting stabilizes and maximizes the insulation's loft PFC-free DWR resists moisture Left pocket doubles as a stuff sack for convenient stowing Winter 2023/24 product Equipped With PFC-Free Durable Water Repellent (DWR) Like standard DWR, PFC-free DWR is a fabric treatment that improves the water-repellency of the outer layer of the material while maintaining its breathability—but without PFCs (perfluorinated chemicals). PFCs decompose slowly and negatively impact the environment. According to the EPA, PFCs also harm human and animal health, and they can be ingested through air, water, and food. PlumaFill Patagonia’s revolutionary lightweight PlumaFill insulation replicates the structure of down in a continuous synthetic insulation material that offers the warmth and packability of down, but with the warm-when-wet performance of synthetic insulation.
