A hat that covers your ears is commonly called an "earflap hat" or "beanie with ear flaps." There are several types of hats designed to cover the ears for warmth, including:
- Trapper hat – Has ear flaps and is lined with warm materials like fur or fleece, originally worn by hunters and trappers in cold regions.
- Ushanka – A Russian fur hat with ear flaps that can be tied up or worn down for extra warmth.
- Chullo – A traditional Andean hat made of wool with ear flaps, often with colorful patterns and tassels.
- Balaclava – A full head covering that leaves only the face or parts of the face exposed, often covering the ears and neck.
These hats are designed for cold weather and offer protection against wind and cold temperatures.
