This high-performance white long-sleeve base layer is designed for motorsport professionals and enthusiasts, featuring a sleek, form-fitting cut optimized for layering under race suits. The garment prominently displays the APX GP Expensify logo at center chest—a stylized 'APX GP' with 'Expensify' beneath—alongside key sponsor logos including Mercedes-AMG, IWC, Tommy Hilfiger, OMP, Shark|Ninja, MSC Cruises, and Esports branding on sleeves. Constructed from lightweight, moisture-wicking technical fabric (likely polyester/spandex blend), it offers breathability, stretch, and rapid sweat dispersion for optimal thermal regulation during intense activity. Flatlock seams minimize chafing, while the crew neck and ribbed cuffs ensure comfort and secure fit. Ideal for track days, pit crew wear, or as premium streetwear for F1 fans, this piece bridges professional racing functionality with contemporary sport-luxe aesthetics. The clean white base highlights bold black graphics, making it versatile for both on-track utility and off-track styling in casual or semi-formal settings.
