KONUSTEX K-MOVE 25 T-shirt outdoor hunting shirt for men in black polypropylene

For all those who experience the outdoors here is a line with a sporty fit designed to offer targeted solutions for all seasons. For spring/summer the garments have a thin but compact structure and a soft feel like silk, allowing for quick dispersion of sweat, for winter a fabric with a very fine internal sponge which, in addition to facilitating the escape of sweat, traps a greater quantity of air for high thermal performance.

Polypropylene, what material is it? Striscia la Notizia also talks about it....
