World-class dark brown Argentine leather with powder blue & white nylon thread, artfully hand-stitched in Buenos Aires. DON&&';;T KNOW YOUR SIZE?A good rule when choosing a Zilker Belt is to go 2" larger than your pants&'; waist size. So if you typically wear size 34 jeans, order a size 36 belt. For odd sizes, we suggest ordering 3" larger to be safe (ex. - choose a size 38 Zilker Belt for size 35 jeans). Check out our Sizing Chart for more details.
