Polar fleece

[2] Polar fleece originated in Massachusetts in 1979 when Malden Mills and Patagonia developed Synchilla (synthetic chinchilla).

High loft fleece is warmer because it traps tiny air pockets which holds body heat.

To prevent high pile fleece from matting, they can be brushed regularly (which also removes dirt) and hung rather than folded.

Fleece readily generates static electricity, which causes the accumulation of lint, dust, and pet hair.

It is also susceptible to damage from high temperature washing, tumble drying, or ironing under unusual conditions.

[19] The release of these microfibers into the wastewater is proportional to the microplastic pollution in soil, marine, and freshwater habitats.
