This gear really works! Bug clothing is made of a fine polyester mesh that forms a formidable barrier between mosquitoes (and black flies!) and your skin. It’s a simple concept. I’ve had a set, jacket and pants, for a few years now (the link is to Lee Valley, where I got mine, but I’m sure it’s available elsewhere as well). I don’t think I’ve ever worn the pants, because I’m usually in the field in overalls or jeans. But I can recommend the top. With hood up and zipped, it’s light, loose, and soon forgotten about, as are the biting bugs. In fact, only the mesh over your face takes a few minutes getting used to before you stop noticing it. Just don’t spit!
