High performance 650 fill Berghaus Hydrodown® continues to insulate even when wet and the jacket is wrapped in water and wind resistant Pertex® Quantum fabric, which allows the down to fully loft and enhances warmth further. The hood, internal neck baffle, a big front hood baffle, and adjustable hem all boost warmth and keep out the draughts. A classic Berghaus ‘Trango’ quilt pattern and shorter length cut complete this insulated jacket.
