A Reversible Hoodie Hides a Warm Puffy Vest On the Inside

For those times when it's a little chilly to step outside without an outer layer, but not quite cold enough for a jacket, Nike's Tech Fleece Aeroloft Windrunner serves as an extra-insulated hoodie thanks to a warm built-in vest filled with 800-fill down. And for those times when the puffy vest look isn't quite working for you, the hoodie can be reversed to create a subtler fleece look, without sacrificing warmth.
