The Women's BugsAway® Wanderlux Serra Long-Sleeve Shirt will keep you comfortable on trail hikes long and short. If the temps rise, moisture-wicking drirelease® technology keeps you dry, while odor-reducing SILVADUR™ antimicrobial treatment means less washing and more wearing. Its stretch fabric won't hold you back, while the gusseted mesh underarms and back pleat detail enhance breathability when you're testing your limits. Bug-blocking Insect Shield® treatment gives you the invisible, odorless protection of Permethrin and lasts up to 70 washes. Sunny day? Built-in UPF-20 sun protection shields your skin from dangerous UV rays. The drop-tail hem provides extra coverage and won't ride up if you're carrying a pack.
