description Polar Fleece Overview
Polar fleece is a soft, lightweight pile textile generally made from polyester and used as thermal insulation. Developed by Malden Mills around 1979, it traps air within its raised fibers, dries relatively quickly, and can retain insulating value when damp. It is widely used in jackets, pullovers, blankets, hats, and outdoor layering systems, although it offers limited protection from wind unless combined with another fabric.
help Polar Fleece FAQ
What material is polar fleece made from?
Polar fleece is a soft, lightweight pile textile generally made entirely from polyester. This synthetic makeup allows it to trap air within its raised fibers, providing excellent thermal insulation for jackets and blankets.
When was polar fleece invented?
Polar fleece was developed by the American textile manufacturer Malden Mills around 1979. The company, later known as Polartec, created it as a synthetic, lightweight alternative to traditional wool.
Is polar fleece waterproof?
No, polar fleece is not waterproof, but it does dry relatively quickly and can retain its insulating value even when damp. Because of its open pile structure, it is highly breathable but will allow wind and rain to pass through easily unless treated with a durable water repellent finish.
Does polar fleece shrink in the wash?
Because it is made of synthetic polyester fibers, polar fleece generally does not shrink when washed in cold or warm water. However, exposing it to high heat in a dryer can cause the fabric to melt, pill, or become permanently distorted.
