Men's Insect Blocker™ Knit Long Sleeve Shirt is rated 4.0 out of 5 by 4.
Rated 4 out of 5 by from UV Protection I bought this shirt mostly for UV protection so I did not have to keep putting more sun block on. The insect blocker seemed like a good bonus until I found out it was a chemical treatment and not a difference in the material that made it difficult for mosquitoes to penetrate the shirt. Because of the chemical treatment it is not recommended you wash the shirt with other clothes and the chemical has a life span of 70 washes. I think Columbia needs to put up more info on the Insect Blocker to help guide customers decisions. Overall the shirt does what I mostly bought it for which is to block out UV, but I would have bought the Omni-Freeze shirts instead if I knew more about the insect blocker.

Rated 5 out of 5 by from Great Shirt! I bought this for my husband - we are big fans of the Insect Blocker line - and he loves it! It's lightweight and cool, not heavy or stuffy feeling while wearing it, and the Insect Blocker technology works great! The long sleeves are great for keeping mosquitoes away from your arms. This shirt does fit a little big but not big enough to order a whole size up. Just fits looser than a typical shirt.

Rated 3 out of 5 by from Very hot This shirt was tightly woven and didn't breathe at all. I expected more breathe ability with the omni-wick, but it was just too hot. I don't know about the insect prevention because I bought it for Machu Picchu but there were no bugs when we were there.

Rated 4 out of 5 by from Nice bug shield. Very nice shirt, and more affordable than previous versions, but this shirt does run big. I own other Columbia shirts that are similar material and also a size Large, and I put them on first, then this shirt over them, and it was inches longer/larger. I really wished i'de gotten this in a Medium. Other than that, everything else is great! Materials are of good construction, colors are sharp and accurate, technology works as described!
