Time Release Protection means DEET is slower to evaporate and provides protection after others have dissipated - up to 12 hours of protection against mosquitoes.Ultrathon's Time Release Protection gives the user a balanced mix between concentration of DEET and long lasting protection. Advanced 3M formulation creates an effective barrier that repels mosquitoes that may carry West Nile Virus, and ticks that may carry Lyme Disease. In the mid-1980's, the US Military contacted 3M to develop a better form of protection based on 3M unique Time Release Technology. The resulting product, Ultrathon Lotion, quickly replaced their current DEET product and is still being used today by troops in all areas of the world.6 ounce size - up to 8 hours of protection - 25% DEETSprays upside down for total coverage - with an outdoors scentTested in the harshest environments in the world - the Central American JunglesUnique technology provides longer lasting protection with less DEETSplash & Sweat resistant to ensure consistent protection through all your outdoor activities Model Number: SRA-6UPC: 051131677777Please note that we are unable to ship this product by any type of express air services.
