This high-performance running cap features a lightweight, breathable ripstop nylon construction with extensive laser-perforated ventilation across the crown for optimal airflow during intense activity. The minimalist black design is elevated by collaborative branding: a bold white 'OLB' logo in a distinctive triangular outline, accompanied by 'OLB STUDIO' and 'OLB LABORATORY' text, plus the iconic Human Made signature script logo positioned below—confirming this as a limited collaboration between OLB Studio and Nigo’s Human Made. The adjustable rear strap with plastic buckle ensures a secure, customizable fit for all head sizes, while the curved brim provides sun protection without obstructing peripheral vision. Ideal for runners, trail athletes, and streetwear enthusiasts seeking functional sportswear with avant-garde design credibility. Its sleek silhouette transitions effortlessly from training sessions to urban exploration, embodying Japanese street-sport aesthetics with technical precision. The perforation pattern is strategically dense at the top and gradually thins toward the sides, balancing breathability and structural integrity. Crafted for summer and warm-weather use, it resists sweat absorption and dries rapidly, making it a staple for active lifestyles where style and performance converge.
