Go where the trail takes you in the lightweight Men's BugsAway® Monto Long-Sleeve Shirt. Polyester and nylon combine to offer moisture-wicking, quick-drying, and abrasion-resistant performance. Part of our collection of Permethrin clothing, its invisible, odorless, and bug-blocking Insect Shield® treatment lasts up to 70 washes. Built-in UPF 50 shields your skin from harmful UV rays. Vents on the back and shoulder seams enhance breathability, and offset shoulder seams won't chafe under your pack. This collared shirt features double chest pockets that stow small hiking gear.
