For the best in all-weather scents, try the Code Blue 2 fl. oz. Whitetail Estrous Urine Gel. Collected from a single estrous doe, the gel will give you the same great scent without readily evaporating, freezing or washing away. Plus, it comes with a special applicator built into the bottle's lid to allow you to disperse the scent without contaminating it with your own scent.
