The Quadcube Insulated Shirt doesn't sport a quilted design just for looks. As its name gives away, it is an insulated button up shirt that will ensure men stay extra toasty this winter season. The shirt is insulated with 40 grams of PrimaLoft military-grade synthetic down lining for warmth even when wet. Now that's impressive.
A collaborative effort between New York City-based technical menswear label Isaora and Michigan's Ghostly International, the Quadcube Insulated Shirt also regulates body heat and pulls moisture away from the body, which is perfect for both casual and active use. To make it even more functional than it already is, the Quadcube Insulated Shirt packs up into its own pocket for easy portability. Graphic designer Jakub Alexander designed the special collaboration logo, which forms a jagged mountain.
