shoulders to enhance mobility when hunting. The loose shoulders also permitted a hunter to pull their arms out of the sleeves and into the coat against the body for warmth without taking the coat off. The closely fitted hood provided protection to the head without obstructing vision. The hem of the outer coat would be left long in the back so the hunter could sit on the back flap and remain insulated from the snowy ground while watching an ice hole while seal hunting, or while waiting out an unexpected storm. A traditional parka had no pockets; articles were carried in bags or pouches. Some parkas had toggles called on which a pouch could be hung. Parkas for women are called and have large pouches called for carrying infants. Textile scholar Dorothy Burnham described the construction of the as an "engineering feat." Numerous regional variations of the exist, but for the most part, the hem is left longer and cut into rounded apron-like flaps, which are called in the front and in the back. The infant rests against the mother's bare back inside the pouch, providing intimate skin to skin contact for the mother and child. A belt called a is cinched around the mother's waist on the outside of the , supporting the infant without restraining it. At rest, the infant usually sits upright with legs bent, although standing up inside the is possible. The roomy garment can accommodate the child being moved to the front to breastfeed or eliminate urine and faeces, and can be reversed to allow the child to sit facing the mother to play. In the past, the would be made smaller and narrower for widows or women past their childbearing years, who no longer needed to carry children. In the western Arctic, particularly among the Inuvialuit and the Copper Inuit, there is another style of women's parka called the "Mother Hubbard", adapted from the European Mother Hubbard dress. The Inuit version is a full-length, long-sleeved cotton dress with a ruffled hem and a fur-trimmed hood. A layer of insulation – either wool duffel cloth or animal fur – is sewn inside for warmth, allowing it to function as winterwear. Although the Mother Hubbard parka only arrived in the late 19th century, it largely eclipsed historical styles of clothing to the point where it is now seen as the traditional women's garment in those areas.
