These wipes feature an effective 20% picaridin mosquito and insect repellent in a convenient towelette. We recommend DEET for use in the Sierras against mosquitos and flies. The wipes make it super easy to apply repellent just where you need it and avoid spraying on gear or in your eyes. Plus, the risk of repellent leaking into your bag is much lower than with spray bottles. Contains 4 individually wrapped wipes per package.
