This wearable fan features five adjustable speeds, from a gentle sleep mode to a powerful breeze for any setting. It runs as quietly as 20 decibels and lasts up to seven days on standby. Its 360-degree airflow cools your entire head and neck, while patented centrifugal technology keeps long hair safe from tangles. A smart LED screen shows all settings clearly, and the flexible memory silicone extends up to 45 degrees for lasting comfort without neck strain.
