Above is my attempt to quiet my gear bag. I basically had my mother in law sew a fleece replica of the original NT bag. Unfortunately, it wasn't strong enough by itself and the D ring pulled through. I then cut slits on either side of my fleece bag and put my NT bag inside. Personally,I put all my stuff in the bag, hook my NT back seat/band to the Dring and the swivel clip and throw it over my neck. So far it's worked great and u don't have the back/seat band hitting you in the calves.
