BASTION DOWN GILET
Insulated goose down gilet
Regular price £295 Sale price £177
Men's highly insulated and packable, 900 fill power, goose down gilet in camouflage constructed from Pertex® Quantum fabric. Features targeted baffle system that maximises insulation around your body's core and breathability under your arms. Suitable for layering 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. Baffles optimised for core insulation while maintaining arm breathability. The Bastion Gilet also features a totally unique ThruDark camouflage designed by our in-house team.
