Fortunately, humans are smarter than insects. Otherwise, how could ExOfficio have ever come up with this jacket? The BugsAway Damselfly is a lightweight, high-coverage top. Primarily constructed with mesh and woven panels for stability, its drawcord hood, cinchable hem, and elastic-bound sleeves are uninviting to bugs, and the whole garment stuffs into the left front security pocket for easy packing.BugsAway apparel is treated with Insect Shield, giving you invisible, odorless protection just by putting on your clothes. The treatment is bound to fabric fibers, so it stays in your clothes not on your skin and lasts through 70 washes. Ants, flies, chiggers, midges, and ticks don`t like it, and neither do mosquitoes, which can transmit insect-borne diseases such as Zika, Chikungunya, dengue, and West Nile viruses.
