Valhalla Pure’ polartec jacket

Valhalla Pure’ Polartec zip up jacket in size S/P. Now I wear a medium and it fits me so I would say it’s meant to be a looser fit. The back center measures 28 inches long. This has zippers that open in the arm pits, 2 side zip pockets and 2 inside mesh pockets, no zipper. This is a soft thick fleece and the color gray with the slightest tint of lavender.
