Made for the outdoor adventurer, the ExOfficio Men’s BugsAway Covas Long-Sleeve Shirt will keep you protected against pesky, potentially disease-carrying bugs. Lightweight and quick-drying, the collared shirt features technology to keep you comfortable and focused. A UPF-50 rating protects you from the sun’s dangerous UV rays, so you can keep exploring all day long. 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.
