Mittens with separate thumbs were used for keeping the hands warm in winter. They usually have the hair on the outside at the back of the mitten, which can be held against one's face to keep it warm. The mittens usually are quite short, as the fur trim on the sleeves of parkas protected the exposed wrist.

"Noulloumalik's mittens are of white walrus hide, as white and silky as fine wool." (Émile Petitot, quoted in Savoie, 1971: 172)
