Wear the same 23-ounce jacket whether it's slightly cool or downright frosty outside: A new North Face coat becomes more than a third warmer when it's turned inside-out. Its versatility comes primarily from the way the insulation is sewn. The quilted squares on the metallic -- or cool -- side have small pockets at their edges. When worn on the outside, the pockets stretch open and allow air to flow in and out. When reversed, the jacket pushes the pockets together and traps air inside them, providing greater warmth.
