Mittens

Mittens are a type of handwear designed to keep the fingers warm by enclosing them in a single compartment, with the thumb placed in its own separate tunnel. This construction concentrates warmth and reduces exposed surface area, trading some dexterity for better insulation compared with gloves.

Most mittens have an outer shell made of wool, leather, or synthetic fabrics, with an insulating lining such as fleece, wool, or down. The inner lining adds comfort and moisture management. The cuff can be knit, fabric, or leather and may be elasticized or extended into a gauntlet to seal out cold air. Some mittens feature waterproof or windproof shells for wet or windy conditions.

Various styles exist. Standard mittens suit casual wear and winter activities, while trigger mittens incorporate a separate pocket for the index finger to allow greater dexterity for tasks such as shooting or using devices. Convertible mittens can be worn as standard mittens or flipped back to expose the fingers. Baby and children's mittens are sized for small hands and often include safety features such as strings to prevent loss.

Mittens are used in cold climates worldwide, including for skiing, snowboarding, and daily winter wear. Care typically involves hand or machine washing according to material, followed by air drying away from direct heat. Modern mittens range from simple knitted wool designs to technologically engineered shells with advanced insulation for extreme cold.

Historically, mittens have been found in many cultures and have become a staple of winter apparel in Europe, North America, and Arctic regions.
