The Women's Cirrus Alpine is one of Rab's most versatile insulators for year-round alpine adventures. From summer alpine climbs to winter hikes, the Cirrus Alpine keeps warm with Primaloft Silver's soft, packable insulation. A Pertex Quantum Ripstop shell ensures wind- and water-resistant protection from the occasional spindrift. The Cirrus Alpine has a regular fit to make it easy to add it over a baselayer or under a rain shell.
