Can triathlon t-shirts help manage moisture during long-distance events?

Moisture management is crucial during long-distance triathlons. Custom t-shirts are printed on performance fabric blends, including moisture-wicking materials that help athletes stay dry and comfortable. The custom printing process preserves the base fabric's inherent performance properties, ensuring your personalized shirt supports you through swim, bike, and run segments.

Are race-cut t-shirts designed differently from standard athletic wear?

Race-cut t-shirts differ from standard athletic wear through a more streamlined design. These slim-fit shirts feature a tighter torso and shorter sleeves to reduce drag during competitive events, enhancing aerodynamic performance. Standard athletic cuts offer a looser, more relaxed fit for training comfort. Fourthwall's custom printing works beautifully on both cut styles, letting triathletes personalize their gear.
