This wind sheltering system was designed using the same pattern as our world class Rough©/Blackrak© model anoraks. After testing numerous types of canvas we decided on a 15oz waxed 100% cotton duck, sourced from a certified USA contractor. The front kangaroo pocket comes standard and carries left and right d-ring receivers sewn on the inside. Given it’s full length we added left and right side slits to facilitate access to your pant pockets or side arms. This garment is designed to repel water and provide excellent protection from the wind. With little care, this anorak will provide years of dependability and is built to last a lifetime. Please call us before you checkout if you reside in remote areas and need your order expedited priority in order to meet bush plane schedules.
