Poly Twill Fabrics are often used for sturdy work clothing or durable upholstery because of its strength and durability. Twill also recover from wrinkles better than plain-weave fabrics do. When there are fewer interlacing, yarns can be packed closer together to produce high-count fabrics. In twill and higher counts, the fabric is more durable and air- and water-resistant.

Thinsulate is a trademark of the 3M Corporation, for a type of synthetic fiber thermal insulation used in clothing. The word is a portmanteau of thin and insulate. The material was first sold in 1979. Thinsulate fibers are about 15 micrometers in diameter, which is thinner than the polyester fibers normally used in insulation for clothing such as gloves or winter jackets. Advertising material for Thinsulate suggests that Thinsulate is more effective due to the increased density of fibers with decreased size of fibers compared with more traditional insulation. Like most insulation materials, the gaps between fibers not only reduce heat flow, but also allow moisture to escape.
