I’ve been waiting for a turtle or mock turtle for years! Love the fit and expecting great wear like everything else I’ve owned over the years.

I’ve been a huge fan of the Unbound Merino t-shirts. Seems silly to spend $95 for a t-shirt, but paired with $15 Costco jeans, it’s an awesome daily uniform for those of us who get to pick what we wear! Every time you buy something from Unbound, they send you a survey. For 4 years I’ve been saying that a long sleeve mock T was missing from their line. The regular long sleeve T is fine, but to me it looks like long underwear. It just doesn’t work for me. But this new offering does! I ordered 2 when I got the announcement, and I really like them. The collar feels a little high, but it looks about right in the mirror. Better to be 1/4 inch too high than 1/4 inch too low. The sleeves are a little loose and long in the forearm, but I think they are meant to be worn pushed up, and the shirt looks great that way. I’ve been ordering XXL in everything Unbound and the fit is intentionally maybe just a little boxier than the T-shirts usually are. I’m an XL in almost everything from the US. Talk about a versatile travel garment? This shirt can be anything from under a suit coat at a swanky event to a base layer under motorcycle gear on a cross continent tour. Just as functional as a Smartwool or Icebreaker, shirt, but way, way more fashionable for city wear. And then the fabric? It’s that typical “Oh. THIS is REALLY nice” feeling you get from a high end merino garment.
Super soft, and just the right drape and weight.
Great work Unbound! This is what I’ve been…

I've been a customer for the past four years; shirts, boxers, pants, button downs and I've found all Unbound apparel unbeatable. As a "hard wearing" customer, I put Unbound to the test every day. Yes there are other "GOOD" merino products out there, and I've tried them all. But if you want "GREAT" merino quality and design nobody can match Unbound.

First I tried out the t-shirts and found them irresistible. Then I got into the button down long sleeve shirts. (Love those, but wish there were more colors.) I saw there's a thin mock wool turtleneck now so I ordered one to try and for sure, this is another hit.
Just wash any of these products in cold water and line dry and they will really last. My tip is, no warm water or dryer and you'll really enjoy these products.

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.

A modern classic in Merino wool.
- High neck design suits both dressier settings and understated moments.
- Versatile style with no flashy logos.
- Quick-drying fabric keeps you comfortable.
- Outperforms cotton and synthetics.
- Pack less with wear that doesn’t require washing after every use.
“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 (17.5 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, your body heat can pass through the space between our superfine, woven fibers, regulating your body temperature while keeping you cool and comfortable.
Ready-to-Go Wrinkle Resistance
A Merino wool fiber resembles a tightly coiled spring, also called a crimp. Pull it and it will recoil back into shape every single time. You’ll never need to iron this dress.



EASY CARE
You won’t have to wash this shirt much at all. However, when it comes time for a refresh, simply add it to your load at the cool temperature setting, 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.
- Made in Green OEKO-TEX® certified which guarantees this item was manufactured in environmentally friendly, socially responsible facilities.
- 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!

Jonathan Goodman
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.
Jonathan Goodman

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.
Eric J.

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.
James “Iron Cowboy” Lawrence

Ken S.
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.
