Be careful, Boulder Boots (desert tan) are made of nylon, not cotton, and will burn/turn darker if it is applied with a heat gun to soak into the fabric. Though can be lightened afterwards if scratched with your fingernail. Best of Luck! This product does work great with actual canvas products (thick black) and if not heated creates a beautiful waxed/velvety texture on hats (grey brim, black trucker back).
