The Optimistic Runners Race Singlet in Blueberry is a refined version of the brand's signature singlet. It is designed for race day, when every detail of comfort and freedom of movement counts.

Its open-back construction enhances scapular mobility, so your arms and shoulders can swing naturally stride after stride. The lightweight, breathable and perforated fabric keeps air flowing and helps you stay cool and comfortable when the effort builds, while its quick-drying properties stop it from feeling heavy as you sweat.

Reflective details improve your visibility in low-light conditions, which is useful for early starts, evening sessions or races that begin before sunrise. The Blueberry colour gives it a distinctive look on the start line and pairs well with neutral running shorts.
