The focused geometry and edgy contrast stitching of the Marmot Women's Portillo Jacket hearken back to an earlier age, but slip this baby on and it's clearly the 21st century. Constructed from MemBrain(R) fabric that's both impervious to the elements and highly breathable, it's enhanced with an enviable list of resort-ready features. Underneath, a layer of our cutting-edge Thermal R(TM) synthetic insulation delivers lasting warmth without bulk.
