Use it as a layer on the mountain, rock it by itself downtown, or toss it into a pack for your next adventure. When winter hits you can do just about anything in the Rab Microlight Down Jacket. In fact, the only thing you won't want to do is get caught without it. This versatile insulator is filled with recycled 700-fill down that's been given a special hydrophobic treatment to ensure that it'll dry quickly and retain its loft when you get caught in heavy snows or steady wintry mixes. For lighter precipitation and moderate snows you'll be set without a shell, thanks to the durable Pertex Quantum outer fabric. Pertex Quantum is breathable, wind- and water-resistant to meet the demands of everyday winter weather, and also packs plenty of rugged toughness for mountain environments. Hand pockets are easily accessed with a harness on, and for colder and stormier days, the slim fit slides easily underneath an alpine or ski shell.
