The BLACKYAK Nelore Jacket is made using CORDURA® lightweight Ripstop and CORDURA® Fleece. This jacket has been filled using 700 cuin, traceable goose down treated to be water repellent. The jacket has a great range of use as it is lightweight and has a very small packing volume. You can wear it as a warmer underneath your 3L Jacket or as a warming item. The innovative design and coloration make the Nelore Jacket a real statement.
