Mittens are 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. Mittens are often made from materials like wool, fleece, or synthetic fabrics. Mittens come in various styles and sizes, suitable for different activities such as skiing, snowboarding, or everyday use. They can be found in many colors and patterns, making them a popular choice for both children and adults. Some mittens also feature waterproof or insulated materials for added protection against the elements.
