The North Face Men's Catalyst Micro Jacket is an 800-fill down jacket, making it ready for trips up the mountain. The Catalyst Micro has a special treatment coating the down, called ProDown, making it water-resistant. If you've ever seen wet down, imagine a wet dog. This treatment prevents the wet dog look for longer (than regular down), keeping you warmer. As a stand alone or mid layer, it'll keep your heart happy.
