As the name suggests, the Adventure Medical Ben's Clothing & Gear Insect Repellent Spray is designed to keep our clothes and gear, and thereby ourself, free from insects that may cause viruses and diseases. Its permethrin-infused formula works to repel mosquitoes, ticks, and other insects, and even kills bugs on contact when they land on our clothes, hat, pack, or other gear. Our protection won't fade after one hike or city tour either-the formula bonds to fabric fibers for up to six weeks of protection, and even lasts through several wash cycles.
