Seamless construction and dynamic four-way stretch form the technical foundation of On's Train Flex T-shirt, engineered specifically to withstand the physical demands of high-intensity workouts. Crafted from a recycled yarn composition, the top relies on On AuraFlex – a knit that eliminates friction-causing side seams to support unrestricted movement through lifts, sprints, and interval sessions.
