A Running Shirt, Not Just a T-Shirt
Breaking away from the conventional idea that “running shirts must be made from knit fabrics,” we selected a woven fabric that combines lightweight comfort, flexibility, moisture absorption, and breathability.
Rather than relying on stretch properties alone, the pattern is engineered specifically for running movement, with carefully designed armholes and chest lines to provide both freedom of movement and comfort.
The result is a running shirt that delivers a smooth, unrestricted performance without stress during activity.
IPEKER Cupro / Rayon High-Performance Fabric
The fabric features a high-performance blend of 55% cupro and 45% rayon from IPEKER, a long-established textile manufacturer in Turkey.
By combining cupro’s excellent moisture absorption and release properties with rayon’s breathability and smooth, non-clinging texture, the fabric helps maintain a comfortable microclimate inside the garment during movement.
Its high moisture absorption quickly disperses sweat, while airflow across the fabric surface promotes evaporative cooling. The combination of effective sweat management and cooling performance helps prevent overheating during runs.
Designed with functionality as the priority, this fabric maintains a dry and comfortable feel even during extended periods of activity.
Please note that the beige bleeding-like effect around the red print is an intentional design element by IPEKER and should be appreciated as part of the fabric’s character.
IPEKER
Founded over 100 years ago, IPEKER is a historic textile and printing manufacturer based in Turkey.
With technology and expertise developed throughout its long history, the company maintains consistent quality through an integrated production system covering weaving, printing, and manufacturing.
IPEKER is also committed to sustainable practices, including reducing printing solvents, minimizing wastewater from processing, and utilizing waste liquids generated during production in its own power generation facilities.
UV Protection Function (90% UV Shielding Rate)
Compared with natural fibers such as cotton and linen, polyester has a lower tendency to transmit ultraviolet rays.
By utilizing this characteristic, the material achieves a UV shielding rate of 90%.
Even under intense midsummer sunlight, it helps reduce UV exposure and provides reliable protection during outdoor running.
Functional Details Designed Throughout
A collarless, flat neckline design reduces discomfort during movement and provides a clean, minimal feel.
The front zipper allows subtle temperature adjustments while running, helping maintain optimal comfort and performance.
A COOLMAX® mesh back yoke is placed across the upper back to improve ventilation in an area where heat tends to accumulate.
The same mesh material is used for the chest pocket lining, balancing storage functionality with improved airflow.
Side slits enhance ventilation while improving access to pants pockets, creating a structure that allows natural movement without restriction during running.
