Why We Like It

This shirt is your new secret weapon against pests that can spoil a good time. The Debug UPF Lightness Shirt is truly a multi-tool of upper torso comfort and protection, made with a nylon-polyester blend fabric that’s light, 30+ UPF rated, moisture-wicking and quick-drying. This lightweight shirt floats (off the skin) like a butterfly and packs a mean punch when it comes to insect protection. Treated with Insect Shield® Technology for invisible, odorless protection from ticks, chiggers, midges, and no-see-ums. Button up and adventure on.
