Overview & Obtaining
Tuques are woolly caps worn in colder climates to protect the upper head and ears from the bitter cold and wind chill from the likes of ice sheets and tundras. Tuques can be purchased, crafted, or stripped from Outlanders and Pirates. Unlike cowboy hats and bowler hats, tuques don't provide a social impact bonus.
As a complicated garment, tuques require complex clothing to be researched and can only be made at a hand-tailoring bench or an electric tailoring bench. A tuque requires 25 of any fabric, and 20 work to create. Leathers can't be used to create tuques.
Conclusion & Comparison
Tuques, like parkas, significantly improve minimum comfortable temperature, meaning they're mainly practical for extreme colds of those which can drop below -30 Celsius in Winter (sea ice, ice sheets, tundras, boreal Forests). Compared to cowboy hats and bowler hats, tuques provide much better cold insulation and identical armor, but don't offer any heat insulation or social impact bonus.
