The lightweight Women's BugsAway® Caddis Short-Sleeve Shirt is a great piece to layer beneath an open woven shirt while exploring in frequently changing weather. Raglan sleeves and stretch construction make it easy to move, while the moisture-wicking, breathable fabric ensures you stay comfortable in unpredictable temperatures. Built-in, bug-blocking Insect Shield® treatment gives you the invisible, odorless protection of Permethrin and lasts up to 70 washes, while UPF 50 blocks the sun's harmful rays. An inverted back box pleat and drop-tail hem add style and coverage.
