It's about time - a DEET-free insect repellent that really works! Natrapel 8-Hour provides over eight hours of protection from biting insects and ticks. This effective 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, this product is completely safe on gear and will not melt jackets, fishing line, and other synthetic materials.
