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 pair of shorts much at all. However, when it comes time for a refresh, simply add it to your load at the cold 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."

    Size Medium

    I’m 5’9” and currently around 180 lbs, and the size Medium fits beautifully. My weight has been fluctuating this season, and these shorts have been perfect because the fabric is soft, stretchy, and forgiving without feeling loose or sloppy.

    I specifically sought out merino wool sleepwear because I wanted something natural, breathable, and moisture-managing. I also appreciate that merino is known for being naturally odor-resistant and having antimicrobial properties, which makes it feel like a smart choice for sleepwear and overall comfort.

    As someone with a history of UTIs, breathable fabrics matter to me, especially overnight. These shorts help me feel cool, dry, and comfortable, and they feel much better than synthetic sleepwear.

    The quality is excellent, the fit is comfortable, and I’m already stocking up. I can’t recommend them enough!

    Great for travel!

    I ordered these so I'd have a go-to pajama set for travel and they are great! I'll wear them with an oversized merino tshirt and they are perfect for travel. I'd say they run a little bigger (I normally size up for my tees here) my real size was almost a bit too loose. Super comfy for sleep though so that's fine!

    Soft and cool

    It feels good. A little big for me though. All of UM’s apparel that I’ve tried so far seem to be bigger than an XL which is what I wear. Your mileage might vary though.

    Great sleep shorts

    Love these for summer. Very soft , lightweight and comfortable. Kind of wish they had pockets, but not a big deal. I bought my normal size (small), and the fit is perfect for me. I also bought the matching sleep tank in the same size, which I love as well.
