Men's highly insulated and packable, 900 fill power, goose down jacket in black constructed from Pertex® Quantum fabric. Features targeted baffle system that maximises insulation around your body's core and breathability across and under your arms. Suitable for wear in low single and minus figure temperatures.
Pertex® Quantum uses a tightly woven structure to provide light and soft down-proof fabric that allows full loft for enhanced thermal performance. This structure prevents down shedding while maintaining tear strength and water repellency after repeated washing. 900 fill power goose down provides maximum warmth—fibres are highly breathable, hydrophobic, and highly compressible for easy packing. Features centre front zip with Hypalon pull and zip guard, invisible hip pockets, two large internal stash pockets, left hand internal zip pocket. Hood with dual adjustment for high winds, anchored adjustable hem to minimise heat loss. Baffles optimised for core insulation while maintaining arm breathability. Features unique ThruDark camouflage design lining.
