展开Its about time a DEET-free insect repellent that really works! Natrapel 12-hour provides 12 hours of protection from biting insects and 12 hours from mosquitos 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 12-hour is completely safe on gear and will not melt jackets, fishing line, and other synthetic materials. TSA 3.4oz travel size allows you to bring the maximum amount of Natrapel 12hour insect repellent with you wherever you fly.
