For the fast and light, the Rab Continuum is a firm favourite. It has micro baffles packed with hydrophobic goose down and sewn in this design to stop down migration and cold spots. The goose down has been treated so it will perform even when it gets wet and will still loft and dry quicker than standard untreated fillings. Ultra-soft Pertex Quantum has resilience but allows the down to loft to its full potential and has a small pack volume too. The hood on this Rab down jacket is helmet-compatible and adjusts to create a great insulating fit with flexible Polymer peak. The Rab Continuum comes with its own Pertex Quantum GL stuff sack for convenience and space-saving.
