The Women's The North Face Terra Peak Vest is a synthetic puffy vest for layered warmth. Surround your core with ThermoBall insulation and head out for the day. It's as simple as that, over a base layer, under a shell, or any other combination you see fit. The 100% recycled insulation is lightweight, water-resistant, and toasty. Packable into its own chest pocket, if the weather warms up, you can tuck it into your pack for later.
