A glove (Middle English from Old English glof) is a garment covering the whole hand.
Gloves usually have separate sheaths or openings for each finger and the thumb.
Gloves which cover the entire hand or fist but do not have separate finger openings or sheaths are called mittens.
Mittens are warmer than other styles of gloves made of the same material because fingers maintain their warmth better when they are in contact with each other; reduced surface area reduces heat loss.
Guitar players often use fingerless gloves in circumstances where it is too cold to play with an uncovered hand.
Gloves are made of materials including cloth, knitted or felted wool, leather, rubber, latex, neoprene, silk, and metal (as in mail). Gloves and gauntlets are integral components of pressure suits and spacesuits such as the Apollo/Skylab A7L which went to the moon.
Such workers were already organised in the fourteenth century.
