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 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

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.

Easy Care

Easy Care

Your button-up rarely needs a wash. When it’s time for a refresh, simply add it to your load at the cold, gentle setting and hang to dry.

“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."

    Beautiful fabric, poor fit and style

    The fabric is superb and stays wrinkle free. But the fit seems way off. I am a 16 collar and 39 chest, so should be either a medium or large according to the size guide. A medium is way too big for me. It is also cut like a woman’s blouse, with very soft collar and small cuffs, rather than a man’s shirt. I think it would look a bit odd at a formal occasion - at least in Britain.

    Incredibly versatile

    My only complaint is that I wish they were available in more colors.

    This shirt is extremely comfortable, and handles temperature variation up and down like a champ.

    I only wash it in cold cycle, delicate and hang dry, so it's really lasting forever.

    Great fit

    Shirt fits great. My one request would be at the fabric have a little bit more stretch to it.

    Terrific material.

    The reviews that say this fits small seem to me inaccurate. It would be best to say your measurements when you say what size did or did not fit you. I found that for me, 43 chest, 6' tall, 185 lbs, XL was too big, contrary to what some reviews suggested. I returned and will order L because the material and the light blue color are really great.

    Great Button up

    I was astounded by the sensation of the fabric. I was uncertain about the poplin texture, but I am completely sold. It’s a button-up shirt that I eagerly anticipate wearing.
