An awesome alternative to down coats, the Women's Micro Puff Jacket from Patagonia provides synthetic warmth in a windproof, water-resistant exterior. The Primaloft Eco insulation (100% recycled) provides an amazing warmth to weight ratio and it will continue to deliver warmth even when wet. In the event you get this Patagonia coat soaked, the synthetic insulation will dry in a hurry. Not only can you use the Women's Micro Puff Jacket as a stand alone outerwear layer, but it makes an ideal layering piece under a waterproof shell if you are headed to the mountains.
