Do not be deterred by Trek Ultras low DEET content. Trek Ultra is one of the most technically advanced products on the market offering effective protection from insect bites for up to 12 hours due to its time release technology. It contains 30% micro-encapsulated DEET which is released slowly and lasts longer than any other maximum strength repellent, this reduces the frequency of application and amount needed. Trek Ultra is perfect for expedition and adventure travellers and for those at risk from insect-borne disease, protecting against mosquitoes, ticks and other flying insects.
