Nature’s miracle fabric

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

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.

Merino Performance Piqué

Merino Performance Piqué

Engineered for breathability and movement, this piqué knit blends 60% Merino wool with 40% recycled polyester. Merino provides natural softness, thermoregulation and odor resistance. Polyester adds durability, shape retention and faster drying. The textured knit increases airflow and reduces cling, making it ideal for repeat wear in hot and humid climates.

“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."

    New standard shirt

    I don’t just wear this for travels, I wear it as an every at home shirt. It’s just so comfortable and it looks great. Looks and comfort are often one or the other.

    Looks good and very versatile

    Unbound clothing is my go to for travel clothes. This is the first set of shirts I got for them and I like their versatility- you can dress it up or down. I have also purchased their Tshirts , polos, long sleeves, and underwear . Now, if they only made business casual blazers/jackets I would be set :-)

    Everything you need!

    Bought this shirt for my husband to wear on a 2 week carty-on only trip to Italy this spring. Nice fabric weight, quality construction, and looks great for casual sightseeing to nice dinners out.

    The white is see-through

    This fits true to size, perhaps feeling more on the tailored side. However, the white is very see through. I can see my husband's chest hair and skin. We're taking this on a summer holiday, so I think it'll work over swim trunks and shorts. However, my husband would not wear this to the office or even to dinner. Perhaps the other colors aren't see through, but the white definitely is.

    Love the feel, not the cut

    I feel bad even giving this review, because I've loved all the other items purchased from UM. For 95% of people this is going to be a great shirt, but the cut and the collar just didn't hit the mark for me. The rounded corners an absence of collar stay pockets lacked the structure I was looking for.
