Ideal for extreme tropical conditions and family travel.
Our scientists have developed the technically advanced mosquito repellent Trek Ultra, to give you exactly the same long lasting protection as Trek 100 but with a third of the DEET!
How does Trek Ultra work? It contains micro-encapsulated DEET which is released slowly over the period of wear, which reduces the amount that needs to be applied to the skin. One application continues to be effective for up to 12 hours and it can be used on children from age 2+. Due to the micro-encapsulation technology this mosquito repellent is also more durable in wear and is sweat & splash resistant.
