2XU MT6437D Core Sleeveless Trisuit

The 2XU MT6437D Core Sleeveless Trisuit is a men's one-piece race suit developed for short-distance triathlon. It is intended for athletes who want one garment that can move efficiently through swimming, cycling and running without changing clothing between disciplines. The construction balances lower-body support with a lighter upper section, helping the suit remain purposeful across all three stages rather than being optimised only for time on the bike.

Made for Transitions. The TMF Core Tri Chamois is specifically designed for short-distance racing. Its 65-density foam varies from 2mm to 6mm to place support where it is needed on the bike while limiting unnecessary bulk for the run. Perforations enhance moisture transfer and speed drying, while Skyve technology shapes and reduces the pad towards the edges. This creates a cycling contact layer that provides useful saddle support without behaving like a conventional, heavily padded cycling short once the run begins.

Race-Day Focused. The suit combines stretch, compression and breathable fabrics to accommodate the different movement demands of triathlon. Its sleeveless format leaves the shoulders unrestricted, while the overall construction is intended to remain supportive through sustained racing. For athletes preparing for sprint and other shorter triathlon formats, the Core provides a practical balance of muscle support, cooling, transition-friendly cushioning and accessible race-day functionality.
