Also known as "Thermal Fleece". Pellon Insul-Fleece is made with metalized Mylar layered between polyester fleece. This creates a high-quality barrier that reflects heat or cold (polyester fibers resist conduction while the Mylar resists radiant energy). This special combination is very flexible and easy to sew through, and can be washed and tumble dried with no bunching. Ideal for making pot holders, oven mitts, etc. Can also be used in lunch sacks and grocery totes to keep ice cream and drinks cold or deli food warm. White only. 93.75% Polyester 6.25% Metalized Mylar. 45” width. Bolt has 10 yards.
