Ultrathon - $9.99

Ultrathon was originally developed for the U.S. military for use in challenging environments that require long-lasting protection. Because of its proven effectiveness, Ultrathon is the repellent most recommended by the travel medicine community. The 33% DEET formula is dispersed in a unique controlled-release polymer, which reduces the loss of DEET from the skin surface through absorption and evaporation. When Ultrathon is used on exposed skin in conjunction with permethrin-treated clothing, complete protection against annoying and potentially disease-causing mosquitoes and ticks can be achieved. - $9.99
