Hello!
This liner jacket has inner Gore-Tex membrane layer of polyester.
Gore-Tex materials are typically based on thermo-mechanically expanded PTFE and other fluoropolymer products. They are used in a wide variety of applications such as high-performance fabrics, medical implants, filter media, insulation for wires and cables, gaskets, and sealants. However, Gore-Tex fabric is best known for its use in protective, yet breathable, rainwear.
The simplest sort of rain wear is a two layer sandwich. The outer layer is typically woven nylon or polyester and provides strength. The inner one is polyurethane (abbreviated: PU), and provides water resistance, at the cost of breathability.

This is the same case as with the Austrian army Alpine fleece jacket.
