Men's Merino Underwear & Boxer Briefs

Superior Comfort & Fit: Where Freedom Meets Form

This isn’t your average pair of briefs. We use the same ultra-fine Merino wool as our signature tees, then blend it with nylon and spandex for just the right amount of stretch and support. The result is underwear that conforms to your body like a second skin; snug but never restrictive, soft but structured.

Whether you’re logging long-haul flights, commuting in sweltering heat, or lounging at home, you stay comfortable and distraction-free. There’s no bunching, no sagging, no seams rubbing in the wrong places. Just smooth support that moves with you.

And when you're wearing underwear this good, you feel better everywhere else too.

Why Merino Wool Works So Well

To understand why Merino makes the best underwear for men, it helps to zoom out… way out. Merino sheep have evolved over thousands of years to thrive in extreme climates, from scorching heat to freezing cold. Their secret? Wool that adapts with them.

Each fiber is coated in lanolin: a natural, moisturizing wax that helps repel moisture and regulate temperature. That wool is also naturally antimicrobial, which means it resists odor-causing bacteria without the need for chemical treatments. And it wicks sweat away from the body, keeping you dry and comfortable, even in high-stress environments.

Laboratories have tried to replicate what Merino does naturally, but nothing quite matches the effortless performance of this fiber. When you wear Merino, you're benefiting from generations of natural engineering, transferred directly to your skin.

From our men’s Merino pants and shorts to our boxer briefs, every Unbound piece is designed to make the most of what nature created.

Odor Resistance & Hygiene: Stay Fresh, Wear Less

When you're on the road, doing laundry isn't always an option. You need underwear that keeps you feeling clean even after multiple wears. That’s where Merino outshines everything else.

Merino wool is naturally antimicrobial, meaning it resists the bacteria that cause odor. So you can wear your boxer briefs for days without offending a single soul (including yourself). It’s not magic, it’s just what wool was made to do.

For travelers, minimalists, and anyone tired of overpacking, that means fewer pairs in your suitcase, fewer washes, and fewer worries. That’s more space in your bag and more time to explore.

Moisture-Wicking & Quick-Drying: Because Sweat Happens

Some situations bring the heat. Whether you’re navigating a 12-hour layover, sprinting for a connection, or hiking under a blazing sun, you need underwear that keeps up.

Our lightweight Merino underwear wicks sweat away from your body and dries fast. That means no wet cling, no swampy discomfort, and no having to change halfway through the day.

These boxer briefs pull double duty: staying dry when you're on the move and drying quickly when you’re doing laundry on the go. Hang them overnight, and they’re ready again by morning.

Temperature Regulation: One Pair for Every Season

Merino wool doesn’t just manage moisture, it also manages temperature. That’s what makes it ideal for year-round wear.

When it’s cold, the wool traps heat to keep you warm. When it’s hot, the fibers breathe and let air circulate, keeping you cool. It adapts to your environment and to your body.

That’s why men’s travel underwear made from Merino is so versatile. One pair works in the snow-capped Alps and the scorching Australian outback. It works under layers or on its own. It works because Merino works.

You don’t need summer briefs and winter briefs. You just need the right ones.

Durability & Longevity: Wear After Wear, Wash After Wash

Luxury doesn’t mean fragile. Our Merino wool boxer briefs are reinforced where it matters, stitched for strength, blended for resilience. We’ve engineered them to resist stretching, pilling, sagging, and tearing, even after months of hard use.

That’s what makes them ideal for travel. They’re built to be worn again and again, washed on the fly, and shoved into carry-ons without a second thought.

And unlike cheaper pairs that stretch out or fall apart, these keep their shape. Because when you find underwear you actually love wearing, you want it to last.

Travel-Friendly Features: Engineered for the Carry-On Life

Travel isn’t just about where you go, it’s about what you carry with you. We designed our boxer briefs to take up less space in your bag and more space in your routine.

Lightweight? Absolutely. Quick-drying? Always. Wrinkle-resistant? That too. You can pack two pairs for a two-week trip and never feel underprepared. That’s not an exaggeration, it’s what our customers tell us time and again.

If you’re someone who packs light and moves fast, these are your new go-to. One less thing to think about, and one more thing to rely on.

Sustainability & Ethical Sourcing: Responsible from the Inside Out

Merino isn’t just better for you, it’s better for the planet. Our wool is sourced from farms that prioritize animal welfare, sustainable grazing, and environmentally responsible practices. The result? A product that’s biodegradable, long-lasting, and made with care.

We don’t believe in disposable fashion. That’s why we create long-lasting basics that reduce waste, eliminate overbuying, and align with a more conscious way of dressing.

What you wear close to your skin matters. And so does how it got there.

Material & Technology: Where Nature Meets Innovation

Merino wool is nature’s original high-performance fabric. Soft, breathable, and naturally adaptive, it’s a fiber with a built-in resume.

We enhance it with just enough nylon for durability and spandex for movement. That way, you get all the comfort of wool with the strength of synthetic, and none of the scratchiness or stiffness of typical tech fabrics.

It’s low-maintenance, high-performance, and built to work with your lifestyle.

Lifestyle & Usage: For Travel Days, Workdays, and Everything In Between

These boxer briefs may have been designed with travel in mind, but they fit seamlessly into every part of your life. They’re ideal under gym clothes, workwear, jeans, or joggers. They’re made for movement, but perfect for downtime.

If you like your wardrobe to do more with less, these are essential. One drawer, a few pairs, endless comfort.

Whether you’re hopping continents or heading into meetings, this is the best underwear for men who don’t settle for average.
