For the ultimate adventure travel shirt, pack the BugsAway brisa. With UPF 50 fabric for sun protection, Insect Shield treatment for bug protection, and silvadur for odor resistance, this lightweight, technical shirt makes you feel great no matter where you go. Travel-friendly features include one hidden security zip pocket to hold a passport or phone and sleeve tabs that roll up to a short sleeve. Mesh-lined back yoke ventilation aids air circulation. 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. Silvadur delivers odor resistance for the lifetime of the garment, for less washing and more wearing, so you can pack lighter for your adventure.
