Sleep Better In Merino Wool.
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.

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 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 this shirt 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."

    Love!

    This top fits well and has a nice drape, not too tight. Material is smooth and not itchy at all. Washed well.

    Comfortable!

    Great fit, the fabric is different than my other Marino wool pieces. Almost feels like a polyester mix. Hopefully will be cool. 5’4” 145#

    So Soft and Cooling

    I knew I would love the sleep tank as soon as I put it on. I run hot at night I had been wearing one of my Relaxed Merino V Neck Tanks and was amazed how cooling it was. The sleep tank is so incredibly soft and drapes beautifully.

    Not great for big busts

    I have 34DDD and the top doesn't look great with my larger bust based on the v cut shape. Other than that, it is very soft and comfortable! Wish it worked out for me - returned.

    Excellent for sleep and lounging

    The material is soft and smooth-very comfortable. The cut of the top is a more modest cut which is perfect for lounging without habit to worry about covering up cleavage.
