The Janji AFO HyperLight Cap offers ultra-lightweight performance for all your racing and training needs. Featuring Hyperlight AFO stretch fabric, this cap quickly wicks sweat to keep your head cool and dry throughout your run. Thanks to the flexible foam brim, you can easily stash this hat in a pocket or vest when not in use. As an added benefit, the adjustable bungee in the back lets you secure the cap comfortably to your head, while reflective details increase your visibility while running in low-light conditions.
