It's about time - a DEET-free insect repellent that really works! Natrapel® 8-hour provides 8+ hours of protection from biting insects and ticks. This protection is due 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. 1oz. size is great for packs, purses, or pockets.
