Mittens are a type of gloves that cover the entire hand and have no fingers. They are typically warmer than other types of gloves as they retain more heat. Mittens are available in a variety of materials, including wool, cashmere, and fleece.There are three main types of mittens: fingerless, convertible, and full mittens. Fingerless mittens have a hole for the thumb, while convertible mittens can be turned into fingerless gloves by folding back the flaps on the side. Full mittens cover all of the fingers.Mittens are also available in different styles. Some feature a flap that covers the hand and extends up to the elbow, while others are shorter and only cover the hand and part of the arm. There are also various designs and patterns available.Mittens make a great winter accessory and can be used for skiing, snowboarding, or just walking around in cold weather. They are also useful for keeping hands warm when working outdoors or doing manual labor.
