Z Zegna—the younger, more modern division of Milanese menswear by Ermenegildo Zegna—has combined custom tailoring with state-of-the-art technology to create a bold new activewear jacket.

The Z Zegna Icon Warmer Jacket is designed to keep wearers warm with heating panels laced into a traditional outer shell. Made from merino wool and highly breathable, water-resistant materials, it’s both stylish and practical.

These panels can be controlled with a switch in the pocket to release heat in 40-second intervals, allowing an internal temperature of up to 84 degrees Fahrenheit to be achieved in less than a minute.

The panel’s battery lasts for up to 13 hours of warming and is recharged on the accompanying wireless charging hanger.
