The Patagonia Women's Nano Puff Jacket is a light, weather resistant synthetic insulated jacket that was first built for climbers who needed warmth that holds up when wet. It works as a midlayer under a shell or as a jacket on its own.
Synthetic insulation is the right call when things might get damp, and the Nano Puff has proven itself season after season.
Climbing, hiking, layering and travel. A good packable layer for cool mornings at the crags near Monarch Pass.
