This breathable t-shirt is an ideal choice for warm weather. Made with the innovative Polartec® DeltaTM cooling fabric, the Traverse T-shirt is designed to fit snugly against the skin, improving moisture absorption and quick drying. Unlike traditional fabrics, DeltaTM works more effectively by slightly raising the contact points, creating a soft raised surface instead of being completely flat against the skin. This design promotes better airflow, efficiently disperses moisture and minimizes tissue adhesion when wet. The simple design ensures maximum comfort, especially when used with a backpack. In addition, side mesh panels have been incorporated to improve ventilation, while reflective details provide visibility in low light conditions.
