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.
