The LoopbackSweatshirt

The Sunspel loopback sweatshirt is a modern take on an athletic classic. It was introduced in 2009 by our creative director at the time, Jonathan Anderson. He re-engineered the traditional sportswear design in a softer and more luxurious loopback fabric and perfected it with a clean, contemporary fit.


Originally designed as a practice jersey for American football players in the 1920s, the sweatshirt was lightweight and comfortable but warm enough to stop players cooling down too rapidly. As its name suggests, the traditional loopback fabric is made up of tiny loops of cotton on the reverse side, which provide a soft, cushiony layer of insulation while allowing freedom of movement on the field.

The Loopback Sweatshirt

Originally designed as a practice jersey for American football players in the 1920s, the sweatshirt is a sportswear icon. It was made to be lightweight and comfortable, with its cotton loopback fabric allowing for freedom of movement on the field. Although still associated with Americana today, it has transcended its sporting roots to become a staple of the modern casual wardrobe.

Ours is a refined take with classic detailing, but with some improvements to the original. We created our own fabric for our sweatshirt, dubbed Q40 loopback. It’s tightly knitted from two extra fine yarns, resulting in fabric that’s softer, lighter, more resistant to pilling, and ultimately more luxurious than traditional sweatshirt fabric. It still has the loops on its reverse which give it its name, but they have a softer hand-feel than usual. We’ve also refined the fit, making the body and arms slimmer for a more flattering cut, allowing it to be dressed up or down with ease.
