The BugsAway® Sandfly™ Jacket, featuring Insect Shield® technology, is packable bug protection. This lightweight jacket stuffs into its own security zip pocket. Reinforced shoulders hold up under straps, and the hood protects ears and face. BugsAway® apparel is treated with Insect Shield®, giving you invisible, odorless protection just by putting on your clothes. The treatment binds permethrin to fabric fibers for the life of the garment, so it stays in your clothes—not on your skin—and lasts through 70 washes. It's effective against ants, flies, chiggers, midges, and ticks, as well as mosquitoes, which can transmit insect-borne diseases such as Zika, Chikungunya, Dengue, and West Nile viruses.
