The Softness of Merino, Measured in Microns
The quality of Merino wool is defined by fiber diameter, measured in microns, where smaller means softer.
Unlike many Merino brands, we focus on finer Merino wool, prioritizing the softest, most refined fibers to create an experience of comfort that lasts.

The shorts for every day, all day.
- Less washing makes for easy care and less packing.
- Stretchy, ultra-comfortable waistband.
- Moisture wicking and breathable, keeping you cool and fresh.
- No smell after weeks of wear, unlike cotton and synthetics.
“The perfect T-shirt can see you through almost any situation, and Unbound makes a strong bid for the title with their chic Merino designs.”
"It's the most popular T-shirt in our Merino guide and well-loved by travelers. It's very soft and lightweight, and it packs down to a tiny roll."
“These tees have a sophisticated European elegance to them, thanks to both the material and design. Just looking at them makes you feel chic.”
“Between the flattering fit and the classic style, it's a great option for travel.”
"I may hold off on washing this T-shirt for another few weeks. It miraculously looks and smells like it was just cleaned."

"This is the perfect base layer as it’s super lightweight and is anti-wrinkle and moisture-wicking. This can quickly become your new closet staple at home and on the road."
"I may hold off on washing this T-shirt for another few weeks. It miraculously looks and smells like it was just cleaned."
"Lightweight and breathable, this shirt has a perfectly soft feel. The thin material is moisture-wicking, making this great for layering or wearing on its own."
"Unbound Merino sits at the intersection of travel gear and luxe knitwear, offering wool garments in timeless styles. They use superfine premium Merino wool that’s Woolmark-certified."
"This shirt's wool fibers lock odor molecules within and only release them on washing — which means less washing and more wearing. That makes this the ultimate travel top."



Nature’s Miracle Fabric
Every Merino wool fiber has a waxy coating called Lanolin, which helps wick moisture away from your body, and act as a safeguard against odor-causing bacteria. This is what allows our Merino to stay breathable and dry while smelling and feeling fresh, no matter what you put it through.

SOFTER THAN COTTON
This wool isn’t like your typical itchy sweater. We only use superfine Merino wool, resulting in a luxuriously silky soft feel that’s lighter and more plush than your average Merino or cotton. And unlike most clothes, it'll also maintain its form over time and won’t get ruined after a wash.


Regulates Body Temperature
Whether you’re landing in Seoul or Santiago, the natural fibres of Merino wool are excellent when it comes to regulating your body temperature. The breathable material retains warmth, but not to the point of overheating, providing optimal comfort in any condition.



EASY CARE
Your shorts will rarely need a wash. When it’s time for a refresh, simply add them to your load at a normal or cool temperature setting and lay flat to dry.

- Sustainably sourced from independent, cruelty-free wool farms.
- Bluesign certified for supply chain traceability, a service that helps companies to become more sustainable.

Having an every day outfit I feel good in reduces cognitive fatigue and allows me to put all my focus on the people I love and the things I want to accomplish.

There was no way I could have possibly traveled as lightly as I did without my Unbound Merino gear. I still can’t believe that these clothes feel so good and really don’t smell after so many days worn consecutively. It’s just awesome.

Unbound Merino performs as promised, and has totally simplified how I pack when I travel the world. The shirts are AWESOME and the underwear feels like having your balls cradled by the hands of angels.

I’ve worn one Unbound Merino T-shirt for most of the 18 days I’ve been traveling through Hong Kong and Thailand. Super impressed that this shirt does as promised, it doesn’t smell at all despite no washing.

Perfect for Travel
YOU’LL PACK LIGHTER
With clothing that doesn’t smell after every use, you can pack less, allowing you to ditch the suitcase and travel with just a small backpack.
YOU’LL SAVE MONEY
These days, most airlines are going to charge you for anything other than a carry-on. Start packing lighter and doing less laundry, and save your money for the real experiences.
YOU’LL SAVE TIME
Never check luggage or worry about airports losing your stuff. With fewer but better clothes you’ll blaze through airports like a seasoned pro.
