Your shoulders, chest, and outer arms take the biggest hit when Winter winds start whipping. Luckily, our Women's Muroc Jacket practices zone defense. The upper half is a dual layer of durable, wind-resistant fabric. The lower half, plush 200-weight fleece to trap and circulate body heat. The result? A sleek, lightweight jacket that keeps you warm and wicks away sweat to keep you dry. Killer style is only ever half of the UA equation. As this jacket proves, we also add innovation and performance to everything we build.
