The Women's BugsAway Halo Stripe Long Sleeve Shirt is lightweight, moisture wicking and provides extra ventilation, to make you comfortable while exploring the outdoors! This technical tee features a snap-front closure, one security zip pocket on left side that is big enough to fit a passport in, roll-up sleeve tabs, a mesh-lined vertebrae ventilation system on back, BugsAway technology, and UPF 30, which blocks up to 97% of UVA & UVB rays. 100% nylon. Imported. 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 clothes—not on your skin—and lasts through 70 washes. Ants, flies, chiggers and midges can't stand it, and neither can ticks and mosquitoes, those pesky carriers of many insect-borne diseases. Exofficio's Insect Shield uses Permethrin to provide long-lasting effective, and convenient bug protection.
