The ExOfficio Men's Long-Sleeve BugsAway Impervio Shirt repels a wide range of insects, but of course not the ladies. The fabric is crafted from moisture-wicking, quick-drying, and soft polyester, which inspires hugs on and off the trail. Insect shield technology is bonded to the fibers up to 70 washes, and luckily it's invisible and odorless so no one knows why the mosquitos hate you and love them.
My best active shirts & tees EVER! I love everything from ExOfficio!
