Size guide

XS: Chest 34–36" (86–91cm). Ultra-close race fit for lean frames. Deep sleeveless armholes sit high and forward for total shoulder freedom without riding up during hard efforts.

S: Chest 36–38" (91–96cm). Streamlined sleeveless cut with clean torso drape. Perfect for athletic builds needing maximum airflow and motion without excess fabric catching air.

M: Chest 38–40" (96–102cm). Balanced slim sleeveless fit that contours the chest while allowing muscle flex at pace. Ventilated arm openings enhance breathability for tempo and intervals.

L: Chest 40–42" (102–107cm). Maintains race shaping through sleeveless torso and waist, with added coverage for broader shoulders. Armholes stay secure without gaping on longer torsos.
