The Theo Shirt Jacket combines easy comfort with versatile style. Its onion-quilted body is insulated with Comfortemp® Air Fill, a recycled polyester that provides lightweight warmth without bulk. Heritage details—including antique brass snaps, a leather locker loop, and a subtle ribbon stripe at the back neck—add signature character. Designed to layer over a sweatshirt or sweater on cooler days, it transitions seamlessly into late summer and early fall when worn over a polo or tee.
