No one except the flying, biting nasties will know that this tunic is a bug-fighting dynamo. The cotton-blend woven fabric is perfect for humid days, and dries fast so that you can wash it in the sink, hang for awhile, and put it back on at dinner time. Side ties cinch up the hem for adjustable fit. About BugsAway® 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 clothesâ€”not on your skinâ€”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.
