The Assos Cap Black Series OS is a refined cycling cap designed to combine classic style with performance-driven details for everyday rides. Built as part of Assos’s Black Series, this cap blends functionality, comfort, and understated aesthetics — making it a go-to accessory for training rides, all-weather layering, and post-ride style. Its lightweight construction and thoughtful design make it a versatile piece that complements a wide range of cycling kits.

Constructed from breathable, soft fabric, the Assos Cap Black Series OS sits comfortably under your helmet or on its own when you’re off the bike. The material wicks moisture efficiently, helping keep sweat away from your face and eyes during warm efforts or steady climbs. The classic visor helps shield your eyes from sun, rain, and glare, improving visibility and reducing distraction on bright days and light showers alike. Its contoured profile and stretch fit ensure secure, comfortable wear without pressure points, even on long outings.

Beyond performance, the Black Series Cap adds a timeless cycling look to your wardrobe. The minimalist black design integrates seamlessly with a wide array of kit colors and styles, giving you a cohesive, polished appearance whether you’re rolling to the start line or winding down after a ride. Lightweight and packable, it stows easily in a jersey pocket or pack when not in use, ready to provide protection and style whenever you need it.

Whether you’re layering for changing conditions, guarding against sun and rain, or simply adding a classic touch to your cycling ensemble, the Assos Cap Black Series OS delivers comfort, practicality, and enduring style — all in a clean, performance-ready package.
