Nothing can suck the fun out of your time in the woods like a grip of relentless mosquitos; give em' the what for in the Columbia Men's Insect Blocker Knit Long-Sleeve Shirt. Columbia's Insect blocker basketweave nylon keeps mosquitoes, flies, ticks, ants, chiggers, and no-see-ums at bay, and it retains its effectiveness through 70 washes. And if that wasn't enough, Columbia incorporated its Omni-shade UPF 50 so you won't have to worry about harmful UV rays. Don't think that you're going outside in a suit of armor though, because this shirt is vented throughout the body, so you'll keep cool when you're lugging yourself up the hill.
As soft as your favorite T-shirt but with insect-fighting bug repellent, the Columbia Insect Blocker(TM) Knit Shirt is just right for hiking, traveling or other outdoor adventures.
