Ultrathon™ Insect Repellent was initially developed by 3M for the US Military to provide up to 12 hours of protection for their troops. It is still used today.
A proven formula; Ultrathon™ has been tested in the harshest environments in the world – the Central American Jungles. Provides long lasting protection against mosquitoes, ticks, biting flies, chiggers, gnats, fleas and deer flies.
Ultrathon's Time Release Protection gives the user a balanced mix between concentration of DEET and long lasting protection-providing up to 12 hours of continuous protection.
