When you need bug protection for trail-to-town transitions, the ExOfficio Women's BugsAway Vianna Pants are the answer. Modern, clean styling and a durable, abrasion-resistant fabric will keep you comfortable and looking good, whether hiking an experienced trail or relaxing back at camp. Its UPF-50 rating provides protection from the sun's dangerous rays. When it gets too hot, simply roll up the legs and attach the snap tabs to keep them firmly in place. 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.
