Patagonia Alplight Down Jacket The AlpLight Down Jacket uses NetPlus postconsumer recycled nylon fabric made from recycled fishing nets to help reduce ocean plastic pollution and was designed for cool-weather missions when you need a featherlight insulating layer that packs down small and still keeps you warm.
