A mitten is a type of handwear that covers the entire hand but does not have separate finger openings or sheaths. Generally, mittens still separate the thumb from the other four fingers. They have different colours and designs. Mittens provide greater thermal insulation than gloves as they have a smaller surface area exposed to the cold, but have a trade-off in dexterity.
Mittens are associated with cold weather, children's clothing, comfort and various occupational uses. In the English-speaking world, they also have a cultural association with domestic cats, as in the Three Little Kittens.
Mittens are a common sight on ski slopes, as they not only provide extra warmth but extra protection from injury. They are also recommended as part of extreme cold weather clothing. Oven mitts are worn in the kitchen to protect the hands from hot objects.
