Kiss insect bites goodbye: Why insect-repellent clothing is the best thing since, well, insect repellent

Can clothing alone prevent insect bites? We find out

Lousy weather, leaky tents, terrible Spotify playlists, and warm beer — all great ways to ruin a perfectly good outdoor trip. But nothing completely nukes an epic camping weekend like relentless biting bugs. From ticks and mosquitos to no-see-ums and horseflies, there’s no shortage of bitey creatures looking to put the kibosh on your next getaway. The best insect repellents and bug sprays help, of course. But we can’t help but wonder about the long-term effects of slathering our largest organ (our skin) in DEET and other unpronounceable, industrial-strength chemicals.

That’s where insect-repellent clothing comes in. Today’s best options use a variety of cleverly engineered chemicals, fabrics, and apparel designs to keep even the hungriest and nastiest bugs at bay. We took a deep dive into every option on the market to find the best clothing for repelling insect bites in 2023.

How does insect-repellent clothing work?

We chatted with the folks at Sitka, a Montana-based manufacturer of premium hunting apparel, about how to make the best insect-repellent clothing. Its  is built to fend off bugs and bug bites in the worst, most inhospitable environments (think trekking the Florida Everglades in 100% humidity in July). That’s thanks to a three-prong approach:

  • Bite-reduction fabric: The right tightly knit, stretch fabric can actually prevent a mosquito’s proboscis from penetrating to stop insect bites physically.
  • Minimizing skin exposure: The worst bugs are the ones you can’t see, which is why limiting skin exposure is key. Integrated face masks and long shirt tails (for tucking into pants) help keep most of your body covered. Plus, by pulling socks up over leg gaiters built into insect-repellent pants, ticks and chiggers have zero access to your lower extremities.
  • Integrated chemical repellent: The best insect-repellent clothing is infused with a chemical like permethrin (a synthetic version of a naturally occurring insect repellent) that keeps ants, ticks, flies, chiggers, mosquitos, and even biting midges away.

What diseases or conditions does insect-repellent clothing protect against?

“Insects like ticks and mosquitoes can carry a variety of infectious diseases, including Lyme disease and Rocky Mountain spotted fever,” Sitka tells us. Those are the most obvious ones. Then there are even more serious diseases, like malaria, yellow fever, Zika, and the more recent and horrifying Alpha-gal Syndrome (AGS).

The latter is a relatively new disease. According to the CDC, it’s “associated with tick bites. Evidence suggests that AGS is primarily associated with the bite of a lone star tick in the United States, but other kinds of ticks have not been ruled out.” Its hallmark symptom is that many patients develop an allergy to mammalian meat, including beef, lamb, pork, venison, and others. Yes, you can actually develop an allergy to hamburgers by going out into the wild unprotected against insect bites.

The best insect-repellent clothing options we recommend

There are plenty of decent clothing options for repelling insects while you hike, bike, hunt, paddle, or — whatever flavor of outdoor adventure you’re into. But the best clothing for combatting insect bites combines all of the above technology recommended by Sitka into a single piece. Here are our favorites of 2023:

To state the obvious, the best way to fully protect yourself from insect bites is to cover your skin completely. That means pairing the right top with a good pair of bottoms. We like Royal Robbins’ Bug Barrier Active Traveler Pant. The high-performance, comfort-stretch fabric is designed with a streamlined fit without the awkward bagginess of most men’s hiking pants. It’s a look that moves seamlessly from the office to the streets to the trail. But we especially love the odor-free Insect Shield tech baked into the fabric to fend off buzzing bugs and insect bites.
