Sunspel Loopback Overhead Hoody - Black
Loopback’ is the technical term for the fabric traditionally used to make sweatshirts. It’s a literal description of the construction of the fabric that features loops on its reverse and is also a reference to the original machine that was used to knit the fabric: the loopwheel.
Having originally been developed for sports garments, the loops on the back of the fabric were designed to absorb sweat from your body, passing it into the garment to keep you cool. Conversely, the loopback fabric is designed to trap warm air inside, providing an insulating layer for day-to-day wear.
