As you will notice by its unique design, the Q36.5 Nibali Summer Cap is part of the limited edition Shark Capsule Collection. This cap features the classic look of a cotton cycling cap but is redesigned to be more functional on warmer rides. It uses lightweight knitted polyester and mesh inserts to provide a closer fit along with enhanced ventilation. A polyamide sweatband keeps moisture at bay and helps avoid skin irritation. Made with inspiration from Italian Champion Vincenzo Nibali, the Nibali Shark Summer Cap is a great choice for hot days in the saddle.
