RACE🗲DAY
ITAHARA
Race day is a time to celebrate all those training runs, goals, setbacks, and sacrifices you had to make for yourself and those around you to keep going.
Within turbulent moments that life throws at us, you toed the line and kept on your path to getting mentally and physically prepared. When race day arrives, all those past weeks of training are now a part of you and made you into the runner you are today. You carry with you all the sacrifices and achievements for yourself and others who have helped you become the runner you are today.
Today is “Race Day."


EVERY THREAD MATTERS
Engineered for speed and comfort, the AeroFly Singlet is crafted from ultra-thin, 4-way stretch performance fabric that feels weightless—so light, it’s like wearing nothing at all. Designed with jacquard ventilation, it maximizes airflow and wicks away moisture, keeping you cool and dry through every stride. Plus, Microban® Scentry technology fights odor, so you stay fresh mile after mile.


MINIMAL DESIGN, MAXIMUM PERFORMANCE
The minimal design eliminates distractions with bonded seams—no bulky seams, no stitching, just a smooth, chafe-free fit. Low-cut armholes enhance breathability and allow for total freedom of movement, even on the hottest days.




WEIGHTLESS & NO BOUNCE
With a precision-engineered cut that delivers zero bounce and unrestricted mobility, the AeroFly Singlet lets you push your limits without feeling weighed down. Run light. Run free. Run AeroFly.
