A mitten is a type of handwear designed to keep hands warm in cold weather. Unlike gloves, mittens have a single compartment for the four fingers and a separate section for the thumb. This design allows for better heat retention, as the fingers can share warmth, making mittens particularly popular in winter sports and activities. Mittens can be made from various materials, including wool, fleece, and synthetic fabrics. They come in different styles and sizes, catering to both children and adults. Many people wear mittens while engaging in outdoor activities like skiing or snowboarding, where warmth and dexterity are essential.
