Nature's miracle fabric

Nature's miracle fabric

Merino wool fibers allow it to wick moisture away from your skin, which ensures comfort and moisture management. Merino wool’s complex structure locks odor molecules within the fiber and only releases them on washing. This ensures Merino wool resists unpleasant odors often experienced with other fibers.

Softer than cotton

Softer than cotton

This wool isn’t like your typical itchy sweater. We only use superfine (18.5 micron) Merino wool, resulting in a luxuriously silky soft, shirt that’s lighter and much softer than the average Merino or cotton shirt. It'll also maintain its form over time and not get ruined after a wash, like most clothes these days.

Easy care

Easy care

You won’t have to wash these briefs much at all. However, when it comes time for a refresh, simply add it to your load at the normal or cool temperature setting and then lay flat 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."

    Best Boxer Briefs I’ve Owned

    This was my first purchase from this company, and I’ll definitely be coming back.

    These are easily the most comfortable boxer briefs I’ve owned. The merino wool feels incredibly soft, lightweight, and breathable, and they stayed comfortable throughout the entire day without overheating or bunching up. The fit is excellent, supportive without feeling restrictive, and they hold their shape really well. You can tell the quality is there the moment you put them on. Definitely worth it.

    Great hybrid Underwear

    I have tried multiple merino wool underwear but the quality, comfort and looks of the Unbound merino tops all of them. This underwear is great to wear for the gym, or just daily activities.

    Fast drying and comfy

    Next level quality in merino wool products. Smooth and comfortable. I machine wash in a net laundry bag and then hang or lay flat to dry. They dried easily overnight after being machine washed and hung over the back of a chair! I bought these for my fella who has lots of experience with merino products and gives them top rating.

    comfortabe fit

    they are well designed and constructed so also should last. These will be used on trips because the material allows for every second day washes.
