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.

- 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.

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.

Great quality, though inconsistent sizing has become an issue over my last few orders. Which is disappointing.
