Cool Comfort With A Featherweight Feel.
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 wool 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 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.

Ultralight Merino

Ultralight Merino

Originally developed for fine suiting, this 100% natural Merino finish uses a decatization process—steam and tension applied to permanently set the fabric. It reduces shrinkage, enhances luster, and smooths the surface for a cleaner drape and lasting shape. The result is a sleek, cool hand-feel with added durability—ideal for those who want all the benefits of wool, without the bulk.

“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."

    Perfect Material

    I don’t know how many UM products I have, but I wear all of them all the time (not all at once). To me, they are the most comfortable apparel items I own. I travel a lot, and the care they require (or don’t require) is only a bonus.

    Please try their products.

    Summer light

    Looking for a lightweight T to wear on the Camino de Santiago this summer. I’ve worn the regular T’s for the Tour de Mont Blanc and it was perfect. Looks like just the right weight, feels very soft and comfortable. Looking forward giving it a 600 mile ride.

    Perfectly the same but lighter

    I'm a huge fan of the regular crew neck t-shirt's based on quality and fit. The Ultralight versions are the same, same but lighter. Perfect comfort for those super hot days, without giving up the look.
