An awesome alternative to down parkas, the Men's Micro Puff Jacket from Patagonia provides synthetic warmth in a windproof, water-resistant exterior. The Primaloft Eco insulation (100% recycled) provides amazing warmth to weight insulation 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 Men's Micro Puff Jacket as stand alone outerwear, but it makes an ideal layering piece under a waterproof shell when you are headed to the mountains.
