"The Patagonia Light Gust Jacket is built for cool mornings that warm up fast, shoulder-season errands, or the tail end of a fall hike when the temperature drops before the car. The stretch taffeta shell and full-length front placket work together so the jacket stays comfortable whether the pace is slow or steady. What Our Gearhead® Experts Are Saying:""I reach for this on the days that are too warm for a real puffer but too cool to go without a layer. The 60-gram Thermogreen fill adds just enough warmth without making me overheat on the walk to the trailhead."""
