Bring your tunes with you and enhance any activity with the AERIAL7 SOUND DISK SPORTS BEANIE. The SPORTS BEANIE is made of a light-weight moisture-wicking fabric, and is ideal for physically demanding activities. Push your limits and leave no sweat behind, the SPORTS BEANIE works well in warm weather by quickly drying and evaporating perspiration. Adjustable Sound Disks allow you to place them directly on the ear to be fully engaged in the music or slightly behind the ear to be more aware of the surrounding environment. The SPORTS BEANIE is thin enough to fit under most helmets or can be worn on its own. Remove the Sound Disk after an intense day and toss the beanie into the washer for a fresh clean fit. Don’t miss any important calls with a simple touch of a button on your in-line microphone.
