Mozzies? Well if you travel internationally in the tropics, you hear that word a lot—a slang term for mosquitoes—often accompanied by some kind of swear word. When you’re in a place with hungry mosquitoes it’s always annoying, but when those bugs carry malaria or dengue fever, you need an arsenal of weapons to stay healthy.

This Halo Check shirt with Insect Shield takes ExOfficio’s usual double-duty usefulness to a higher level, hitting all the right points for active travelers and keeping the bugs away as well. This fabric treatment is a no-brainer really once you get past the cost: there’s no odor, no harm to your skin, and no change to the feel of the fabric. Yet it holds up for 70 washings or so. I don’t know about you, but there are very few items of travel clothing I own that have been washed that many times.

The shirt itself has most of the attributes I love from ExOfficio . It’s lightweight nylon that doesn’t wrinkle, it dries quickly after a sink washing, it’s ventilated, and there’s a 30+ SPF sun protection. Provided you’re not in a place that’s super hot and humid, it’ll wick away the sweat. With the color I tried out—the khaki checked one—it doesn’t show sweaty areas too badly either.

As usual, there are lots of nice thoughtful extra features built in as well. It has snaps instead of buttons, which I really like. A mesh liner extends much of the way down the inside. There’s a fabric hook on the back for hanging it up and a flap and snap system to hold the sleeves up when you roll them up. (Rolled up during the day when the mosquitoes aren’t around, down at night to protect the arms.) Each breast pocket has a regular pocket and a handy zippered hidden pocket for stashing some cash or a credit card.

This is a great all-around, double-duty travel shirt that should keep looking good for years and keep the mosquitoes away for however long it takes you to wear it enough to need to wash it 70 times. It lists for $90, but prices will vary depending on who is selling it and what colors aren’t moving. As I wrote this, some colors were selling for around $50, so shop around.

There’s a version for women and a version for men, some in solid colors, others in checked patterns.
