This trail running tank top features POLARTEC® POWER DRY high-performance fabric that keeps your body dry and comfortable across varying exercise intensities. The FROGAERO wind system uses scientifically positioned ventilation zones based on body heat distribution, with back panels that automatically open during movement to release heat and close at rest for warmth retention. Designed with seamless adhesive construction and skin-friendly stitching to minimize friction during movement, plus reflective frog eye logo for enhanced visibility in low-light conditions.
