The Patagonia Lost Canyon Jacket - Women's is an insulated jacket for transitioning in and out of the cold season. The oversized box quilting traps 100g Thermogreen insulation, a 100% polyester, for cozy warmth when hiking chilly weather. The short length layers well, and looks great when back in the city. The 100% polyester taffeta shell features a four-way stretch for relaxed movement, and has been treated with a PFC- and PFAS-free durable water repellent finish. Spend more time outdoors with a full-zip that's up for neighborhood strolls to full-on hikes.
