GOBIK Boundary T-shirt, white
GOBIK Boundary T-shirt
High-performance functional base layer designed to maximize aerodynamic efficiency when worn under time trial suits or racing jerseys with a smooth outer surface.This undershirt, conceived as a functional component within a two-layer textile architecture, transcends the scope of traditional thermal regulation of ordinary thermal underwear. It features sleeves made of three-dimensional textured fabric, strategically developed to modify the behavior of airflow around the body, thereby reducing aerodynamic drag and improving flow stability at high speeds.
Its construction is optimized for positions with maximum aerodynamic demands, especially in a time trial posture or aggressive riding style. In these scenarios, where every saved watt counts, it acts as an active element to reduce the rider's overall resistance. It is an ultra-lightweight, technical first layer designed to turn small aerodynamic improvements into measurable performance gains.
