The green gb is fawking fantastic in the summertime ! The blue (foot powder gb) will also work however as with all mentholated daddy bag dusts it MUST be applied to dry bits. If reapplication is required or if one commits the sin of waiting till six flags rash has started then the yellow gb is a safer bet. Baby powder cornstarch or anti monkey butt powder will all also work however medicated gold bond gives the cooling dryness that I prefer. In the wintertime only the yellow is necessary for this guy but dust is required year round.
