As part of Rab's Ascent collection, the Rab Men's Continuum Hooded Down Jacket excels in harsh alpine environments and downright nasty conditions. Saving serious weight for the long uphill slog, the Continuum's advanced Pertex Quantum GL shell and inner layer use precisely woven nylon yarns 10 denier or less for superlight protection that's virtually windproof 1. 0 cc max and water resistant. 850 fill European goose down traps fiery heat without being bulky, thanks to the jacket's mini stitch through baffles. Additionally, the jacket's down insulation uses a hydrophobic treatment to prevent the insulation from losing its heat trapping loft in damp alpine conditions.
