Who needs an outer shell when your fleece layer can do it all? Cast off that cumbersome outer layer and reach for The North Face Windwall 1, a fleece jacket designed specifically to resist those blustery winter winds. The special 100-weight Windwall fabric is windproof rated at 14CFM and you can't do much better than that. It offers excellent protection from the wind, yet still breathes enough so you don't overheat while skiing, running, climbing or skating. While the outside of The North Face Windwall 1 amounts to a strong force field against the wind, the interior is lined with a fluffy warm layer of fleece and you can make it even cozier by cinching the draw cord at the hem and blocking out the chilly air altogether. Sure, you could use the Windwall 1 Jacket as insulation under a shell, but this middle layer works fine on its own, too.
