TRIMARNI Running Hats (Pre-Order)

TRIMARNI running hats are the world's lightest, most breathable, and eco-friendly training caps on the market today. These feather-light training caps are constructed with extra-large, laser-perforated ventilation holes and feature a proprietary "vented" brim which allows airflow over-and-through to one's forehead. Built with bamboo and recycled nylon, our running hats are naturally hypoallergenic and antimicrobial; so, they won’t smell or cause skin irritation like those constructed with man-made materials.  TRIMARNI running hats are "one size fits many" and can accommodate head sizes between 52-58 cm.
