Made with Taion Fabric, the Inner Down Jacket might just be the perfect layering piece. It’s warm yet still lightweight--thanks to the 800 fill insulation—with a low profile that means it works just as well as a jacket in its own right as it does under something bigger when the temperature really drops. Not only is this jacket lightweight, but it's packable too—and can be stowed away in its own storage bag and thrown in a backpack when the sun comes out. Sort of like a modern-day version of those vintage military down liners, this is a functional, wearable jacket that works for you wherever you need it, throughout the entire year.
