Loopwheeled t-shirts and sweatshirts are the absolute best quality you can buy. Loopwheeling refers to the manufacturing process where fabric is knitted around a cylinder. The only tension in the fabric during the knitting process is the fabric itself, so the result is a low tension weave that retains the natural characteristics of the fabric used. Whilst the resulting fabric is the very best available, the process is labour intensive as a separate loopwheeling machine has to be set up for each size variation required. Loopwheel knitting is slow too, with only around a square meter of fabric being produced by each machine per hour. There are only two dedicated loopwheel knitting factories remaining in the world, both in Japan, and the products on sale here are made by them.
