An American invention of the 1920s, loopback sweat fabric was made as a response and replacement to itchy wool sports jersey tops of the time. 

Sweat fabric came to bear its unglamorous name thanks to its sportswear origin and the loopback construction wicking sweat away from the body during exercise with the garment absorbing the excess moisture.

Loopback sweat fabric nowadays is not only superset and ideal for kids clothes but it doesn’t pill and won’t shrink after washing. Now thats going to keep parents happy!
