Built for running and outdoor activities, the Optimistic Runners Perforated T-Shirt offers lightweight comfort and reliable performance. This version comes in Black.

It is made from a quick-drying, durable fabric with laser perforations on the shoulders and torso for improved airflow and ventilation, helping you stay cool when the effort and the temperature rise. A regular fit combined with flatlock seams ensures a smooth, chafe-free feel, so you can keep your mind on the run rather than on your kit. Reflective details enhance visibility during early morning or evening runs. Versatile and easy to wear, it works for daily training, longer weekend runs and outdoor sessions alike, and the classic black colour pairs with any shorts or tights in your wardrobe.

A dependable tee that will quickly become a regular in your training week.

Optimistic Runners designs its running kit to be practical on the run and clean enough to wear every day, and this piece follows that approach.
