Natrapel provides 8 hours of protection from biting insects and ticks, thanks to its CDC-recommended 20% Picaridin formula. Unlike ineffective DEET alternatives, Picaridin is the only formula that consistently shows equal or better performance than DEET in independent, clinical tests. Even better, Natrapel 8-hour is completely safe on gear and will not melt jackets, fishing line, and other synthetic materials. Individually wrapped wipes let you control the amount and location of repellent to apply.
