Lightweight, 100% polyester moisture-wicking fabric is the best choice for custom running t-shirts. This material pulls sweat away from the skin and dries rapidly to prevent chafing during long runs. Avoid 100% cotton, as it retains moisture, becomes heavy, and causes skin irritation.

Sublimation printing is the ideal method for custom running gear because the ink fuses directly into the fabric fibers. Unlike traditional screen printing, sublimation maintains 100% of the fabric's breathability and stretch. It guarantees that your logos and designs will never crack, peel, or fade from sweat and frequent washing.
