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.

Perfect Fit. Merino Performance.
- Lightweight-meets-compact construction perfect for easy packing.
- Feels silky soft and luxurious against your skin.
- Wrinkle resistant so you’ll always look sharp on the go.
- Casual and versatile style with no flashy logos.
- Dries fast, keeping you comfortable.
As featured in
Nature’s Miracle Fabric
Every Merino wool fiber has a waxy coating called Lanolin, which helps wick moisture away from your body and acts 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 (18.9 micron) 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.


NATURAL AIRFLOW
With Merino wool, body heat can pass through the space between its superfine, woven fibers, regulating your body temperature while keeping you cool and comfortable.
Ready-to-Go Wrinkle Resistance
A Merino wool fiber resembles a tight coiled spring, also called a crimp. Pull it and it will recoil back into shape every single time, meaning you’ll never need to iron this piece.



EASY CARE
You won’t have to wash this item much at all. However, when it comes time for a refresh, simply add it to your load on a cold, gentle setting, then line dry or tumble dry on a low temperature.
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.

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.

James “Iron Cowboy” Lawrence
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.
Ken S.

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.
