The Best Travel Underwear for 2025: Merino Wool Underwear for the Win | I Heart RVing
The last thing you ever want to worry about is laundry. That’s even more true when you’re on the road or off on an adventure! Of course, it goes without saying that the layer closest to the skin is the most important. So, the type of clothing—especially when it comes to the fabric—is key. And that’s where merino wool, and specifically merino wool underwear, enters the conversation.
While it can be difficult to broach the subject of the most comfy undies, it’s worth it to get down to the base layers. Yep—we’re talking undies and bras that are so good you may even forget you’re wearing them.
The right underwear can make all the difference, especially if you’re hiking, biking, and getting a bit of a sweat on. But it’s also important for those long days in the driver’s seat or enjoying slow, relaxing days near camp. No matter the situation or activity, what’s most important is feeling comfortable, staying fresh, and of course, packing light. After all, no one wants to see piles of laundry filling up your storage bin. Fortunately, there are options you really can actually wear more than once—without a funky locker room scent emanating from your RV. (Sorry for the image!)
Without further ado, here’s why merino wool underwear is the ultimate solution for travel. Plus, discover some top picks for men and women, including everything from comfy daily bottoms to supportive bras and breathable base layers.
Why Merino Wool Is the MVP for Travel
Wool? Isn’t that itchy and scratchy? Would I really want that near the parts of my body that never (or at least rarely) see the light of day?
Let’s get this clear from the start: not all wool is the itchy fiber of old. Merino wool is soft—indeed, really soft—and naturally breathable. It also magically regulates body temperatures. That’s why it’s the secret weapon of many savvy travelers and lovers of the outdoors—whether you’re hiking under the hot summer sun or chilling by the campfire as the temps drop.
The real magic of Merino wool underwear, though, is it’s naturally odor-resistant. That means you can wear your undies, bras, and base layers multiple times between laundry visits. This is huge when your laundry situation involves a tiny washer in the corner of your rig or coin machine visits interrupting your trip.
What’s more, merino wool wicks moisture away from your skin. This helps you stay dry even on sweaty hikes and long bike rides. It’s like a natural thermostat that adjusts to your body—keeping you cool when it’s hot and humid as well as comfortable when the weather turns downright chilly.
And let’s not forget: Merino is a renewable, biodegradable material, so it’s a win for the planet and our future, too!
That said, nothing is perfect (not even Merino wool underwear). For instance, it tends to be more expensive than synthetic fabrics. And while it’s durable for what it is, you’ll still want to be a bit gentle with it—especially if you’re using the same set for back-to-back adventures.
The bottom line? If you’re looking for versatile, no-fuss travel undies that can handle all the demands of your RV lifestyle, merino wool should be at the top of your packing list.

Pack smart, stay comfy, and let your adventures (rather than the laundry piles) roll on.
