Rab Cirrus™ takes our expertise in natural down and mimics it closely in a unique synthetic technology. Developed in partnership with 3M, Cirrus™ fibres create loft to give the same warmth-to-weight as 600FP duck down. Rapid drying times make Cirrus™ ideal for mixed and unreliable weather conditions.
“For us, producing the best down products possible is where it all started,” explains Tim Jasper, Head of Design at Rab. “Now with the introduction of Cirrus™, Rab have harnessed decades of down expertise to evolve a synthetic technology that offers a genuine alternative.”
