The everyday fleece that quietly powers the Berghaus layering system.

Story & heritage
Prism is the fleece half of the InterActive story: a simple warm layer designed to work alone or zip into compatible Berghaus waterproof jackets. It has remained visible because it solves the unglamorous problem of adaptable warmth.
The current Prism Micro InterActive Polartec line keeps that promise deliberately straightforward — soft pile, secure pockets, and a shape that layers cleanly under shells.
Materials & craft
Official product data describes Polartec fleece and InterActive compatibility. The micro-fleece build gives warmth without bulk, while the full zip and connection points allow the jacket to become the insulation module inside a waterproof outer.
How to choose & style
Black or dark blue is the useful mid-layer; orange, green and red are the versions that turn a walking fleece into a visible colour note. It looks best when allowed to be functional — half-zipped under a shell, or thrown over a tee without pretending to be knitwear.
