Made with the contemporary longer length, the ExOfficio Women’s Deia Long-Sleeve Shirt is a stylish way to block the sun and the bugs. Lightweight and breathable, the shirt has a vented back yoke with a mesh lining to keep you cool. Its UPF-50 rating will keep you protected from the sun, and its BugsAway® technology will repel pesky bugs. When it gets too hot, simply roll up the sleeves and attach the tabs to keep them firmly in place. The shirttail hem with a drop tail adds a stylish silhouette while providing extra coverage. A hidden zippered security pocket at the right side keeps your passport safely stowed and out of sight. 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.
