High performance 650 fill Berghaus Hydrodown® continues to insulate even when wet, plus this jacket is wrapped in water and wind resistant Pertex® Quantum fabric, which allows the down to fully loft and enhances the effect of the insulation during extended use . Warmth is boosted by the long length, adjustable hood and internal neck baffle. A classic Berghaus ‘Trango’ quilt pattern and other design touches complete this versatile insulated jacket.
