Expedition 50 PRO DEET mosquito repellent is a new and improved formula from Lifesystems which replaces Expedition 50+ insect repellent. The dual-action formula combines the proven performance of 50% DEET with Chrysanthemum Cinerariaefolium Extract which acts as a bite inhibitor to help prevent any insects that land on the skin from biting.
Each application provides 7 hours protection against malarial mosquitoes and it can be reapplied to offer 14 hours total daily protection. Expedition 50 PRO can also be applied to larger areas of exposed skin (e.g. wearing shorts and t-shirt), unlike many other high-strength repellents on the market, making it more practical in real-life conditions.
