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 ONLY WORKOUT TEE
YOU NEED TO PACK.
- Thermoregulating fabric feels cool on the skin, no matter your workout intensity.
- Clean-lined, slim-fit style with no flashy logos.
- Flatlock seams and a tagless back deliver a friction-less feel.
- Merino wool’s antibacterial properties means minimal washing.
- Won't 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."

TRAVEL READY,
JUST LIKE YOU
Unbound Active makes checked luggage a thing of the past. Just one set of gear will get you through every run, rep, and bootcamp without needing a wash.

THE MERINO FEEL
Start sweating in synthetics and you’re in for a clammy, sticky experience. Merino’s moisture-wicking properties help you stay dry, fresh and feeling your best from start to finish.


Eric Stoen
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.

Eric J.
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.

- SMScott M.Verified BuyerI recommend this productRated 5 out of 5 stars7/14/25Best shirt ever!
After traveling 3 weeks in Europe with only this shirt, through heat, humidity, and rain I can say this is the best shirt I’ve ever owned for travel. Will be ordering a second and will give the socks a tryout.

I own most of the merino wool t-shirt and long sleeve brands. Unbound merino wool is by far the best quality wool products. This Men's Active Merino T-Shirt is the best t-shirt, and I purchased multiple so I can wear them daily. Even when it is hot and humid it keeps me cool, and it wicks moisture. I am very happy with this t-shirt. Now I am waiting to purchase more, since they are in stock.

The neck opening is a bit big for my taste, and the sleeves might be a tad short for some, but overall it's a pretty good shirt for doing all sort of exercises.

I feel the same way as before, but this shirt could use more colors, such as undyed (natural), white, and burgundy (or maroon).
