Ultrathon™

3M’s Ultrathon™ is rated #1 by a leading consumer magazine. Its patented 3M controlled release technology works for up to twelve hours - long after other repellents have dissipated. Ultrathon™ creates a barrier that repels mosquitos that may carry West Nile Virus, ticks that may carry Lyme Disease, plus biting flies, chiggers, and more. It also resists perspiration for extraordinary effectiveness.
