which are made of a single piece of skin that wraps up the side of the foot, where it is sewn to the upper. They are loose-fitting to allow for more layers, and may be secured at the top or the ankles with a drawstring or straps. could be covered with the , a kind of short, thick-soled overshoe that provided additional insulation to the feet. These overshoes could be worn indoors as slippers while the were drying out. Historically, men usually rotated between multiple pairs of boots to allow them to sufficiently dry out between uses, preventing rot and extending the useful life of the boot. During the wet season of summer, waterproof boots were worn instead of insulating fur boots. These were usually made of sealskin with the fur removed. To provide grip on icy ground, boot soles could be sewn with pleats, strips of dehaired seal skin, or forward-pointing fur. Boot height varied depending on the task – sealskin boots could be made thigh-high or chest-high if they were to be used for wading into water, similar to modern hip boots or waders. Boots intended for use in wet conditions sometimes included drawstring closures at the top to keep water out. In modern times, boot tops made of skin may be sewn to mass-produced rubber boot bottoms to create a boot that combines the warmth of skin clothing with the waterproofing and grip of artificial materials. Accessory garments Most upper garments include a built-in hood, making separate head coverings unnecessary. The hoods of the Iñupiat people of northern Alaska are particularly notable for their distinct "sunburst" ruff around the face, made of long fur taken from wolves, dogs, or wolverines. Historically, some groups like the Kalaallit of Greenland and the Alutiiq people of Kodiak Island wore separate hats instead of having hoods, in a similar fashion to the clothing worn by the Yupik peoples of Siberia. Many modern Canadian Inuit wear a cap beneath their hood for greater insulation during winter. During summer, when the weather is warmer and mosquitoes are in season, the hood is not used; instead, the cap is draped with a scarf which covers the neck and face to provide protection from insects. Inuit mitts are called , and are usually worn in a single layer. If necessary, two layers can be used, but this reduces dexterity. Most mitts are caribou skin, but
