"The Patagonia Light Gust Jacket is built around 60g Thermogreen recycled-polyester insulation in a stretch taffeta shell light enough to layer under a hardshell or wear as the outer piece on a cool, dry day. The hip length and snap-closure handwarmer pockets make it as useful on a travel day as on a trail approach, and the PFC-free DWR finish handles the light weather in between. What Our Gearhead® Experts Are Saying:""The drawcord hem and full-zip front let me dial warmth on the move. Open up on the climb, cinch down when the wind picks up at the top."""
