I’ve been wearing Unbound Merino- tops and underwear- for my travels for several years. The fit and feel are terrific and I’m able to travel for weeks with just a carry on. Many people are doubtful when I say that but it is absolutely true.

I purchased these for an upcoming trip based on the positive reviews. The fabric is soft and breathable, and they wash up nicely. I expect they will perform great on my upcoming twelve-day trip plan to order a few more pairs before I leave.

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.
METICULOUSLY CRAFTED FOR YOUR COMFORT
- Odor-resistant and antibacterial.
- Less washing with antibacterial clothing that stays dry, clean and fresh.
- Dries really fast, keeping you comfortable.
- Performs better than cotton and synthetics.
- Tag-free band to prevent rubbing.

NATURE'S MIRACLE FABRIC
Merino wool fibers allow it to wick moisture away from your skin, which ensures comfort and moisture management. Merino wool’s complex structure locks odor molecules within the fiber and only releases them on washing. This ensures Merino wool resists unpleasant odors often experienced with other fibers.

SOFTER THAN COTTON
This wool isn’t like your typical itchy sweater. We only use superfine (18.5 micron) Merino wool, resulting in a luxuriously silky soft, shirt that’s lighter and much softer than the average Merino or cotton shirt. It'll also maintain its form over time and not get ruined after a wash, like most clothes these days.
NATURAL AIRFLOW
With Merino, your body heat can pass through the space between our woven superfine fibers, regulating your body temperature and keeping you cool & comfortable.
ENHANCED DURABILITY
When designing our briefs, we went the extra step of blending each Merino fiber with Nylon and Spandex for extra durability and stretch. You'll also find a tag-free, ultra-soft waistband that prevents irritation--definitely a plus for long treks. This is Merino wool underwear designed to take you places.
EASY CARE
You won’t have to wash these briefs much at all. However, when it comes time for a refresh, simply add it to your load at the normal or cool temperature setting and then lay flat to dry.
ABOUT OUR WOOL
- Sustainably sourced from independent, cruelty-free wool farms.
- Woolmark® certified Merino wool means you can expect the highest standards related to fiber content, performance, color fastness, and dimensional stability.
- WRAP (Worldwide Responsible Accredited Production) certified production.
- Tested to ensure our clothing stands up to the rigors of travel and continual use.

Unbound Merino’s shirts are absolutely perfect for travel – good in every situation. They’ve simplified my packing so much that I’m now a carry-on traveler for the first time in my life!

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.
