Insect Shield® Repellent Apparel and Insect Shield® Repellent Gear are revolutionary products designed to provide long-lasting, effective and convenient personal insect protection. The durable protection provided by Insect Shield apparel and gear is the result of years of research and testing. The U.S. Environmental Protection Agency granted registration of Insect Shield Insect Repellent Apparel--the first-ever, EPA-registered insect-repellent clothing. Recently, EPA has granted Insect Shield extended durability cls for its apparel registration, through 70 washings. Seventy washings is nearly three times the longevity of the original EPA apparel registration at 25 washings. Insect Shield apparel and gear products combine the patent-pending Insect Shield process with a proprietary formulation of the insect repellent permethrin--resulting in effective, odorless insect protection that lasts the expected lifetime of a garment. How did permethrin originate, and what are its uses? Permethrin is a man-made version of a natural insect repellent found in certain chrysanthemum s. The Insect Shield process binds a proprietary permethrin formula tightly to fabric fibers--resulting in effective, odorless insect protection that lasts beyond the expected lifetime of apparel. Permethrin has been successfully used in the United States as an U.S. Environmental Protection Agency (EPA)-registered product since 1977, with an excellent safety record. It is used in lice shampoos for children, flea dips for dogs, and various other products, some of which are regulated by the FDA. Which insects does Insect Shield repel? Insect Shield® Repellent Apparel has been proven and registered to repel mosquitoes, ticks, ants, flies, chiggers, and midges (no-see-ums). Insect Shield® Repellent Gear has been proven and registered to repel mosquitoes, ticks, fleas, and flies. The EPA requires extensive effectiveness data to prove a product's ability to repel insects. Many species and varieties of these insects have been tested, including those that can carry dangerous diseases. Tested and Proven Insect Shield technology results from years of intensive research and field study. Numerous studies have confirmed the effectiveness of permethrin-treated clothing as an insect repellent. Insect Shield’s own testing methods follow United States Department of Agriculture (USDA) guidelines, and the results conclusively show that our unique, long-lasting insect protection works. Durable The repellency of Insect Shield apparel is EPA-registered to last through 70 launderings--the expected lifetime of a garment. This is also well beyond the life of most performance finishes commonly used in the technical-apparel industry.
