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."

    Buyer Beware

    I saw a YouTube video on how a person was "all in" with Unbound clothing, especially for travel, which I was interested in terms of packing lighter. I bought a shirt, $20 dollars off, to try it out. Shipping took longer than expected. I receive the shirt and try it on. Looking back at the Unbound website, I do not know if the models are wearing undershirts or nipple guards or what, but to get the full effect of the shirt without an undershirt, it will show off your nipples. The shirt is advertised as "wrinkle resistant" but the shirt out of the box was deeply creased; if I am travelling, I want to avoid the iron as much as possible, so I don't want to risk that. The card in the box said avoid aluminum-based deodorant to avoid staining; I wear aluminum-based deodorant. It also said that the shirt would pill quickly, which I do not like. Finally, since I bought this shirt for $20 off, I now cannot return it, so I am stuck with it. With the lack of disclaimers, I feel that I was duped and now cannot do anything about it. This seems like false advertising. I give it a second star because it did feel comfortable, so that is the only positive.

    Cool and classy

    As we enter the warmer months I wanted a shirt for business trips that was smart but not hot or restrictive. The button up meets this brief really well. Hope the other colours get restocked soon, I really want to buy another.
