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 (15.5 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.

Ultrafine Sleep Jersey

Ultrafine Sleep Jersey

Made from 15.5 micron ultrafine Merino wool, this sleep jersey is cloud-soft and temperature regulating—ideal for uninterrupted rest. Lightweight and breathable at 165gsm, it keeps you cool or warm as needed. Perfect for home or travel, it’s comfort you’ll look forward to every night.

“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."

"I may hold off on washing this T-shirt for another few weeks. It miraculously looks and smells like it was just cleaned."

"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."

    Divine.

    I have three sleep sets: heathered Oat, Fossil and Cinnamon. I live in them at home and when I travel. Paired with my silk, hand-stitched Uzbek jacket and smart shoes, the set is downright glamorous. 54, 172 cm, 75 kilos. I have both the 30 and 28 lengths. I recommend the shorter for travel. Easier to manage in thr loo.

    I could live in these...

    These sleep bottoms are super comfy and fit perfectly. I'm 5'5", 135 lbs and got the Medium. They're lightweight and perfect for sleeping in or just lounging around the house.

    Love these pjs! So comfy. Perfect for trip to Ireland during a heat wave but also when temps dropped to quite chilly!

    Merino Pants

    Honestly I bought these to wear out casually and elevated. Great for traveling as well as they roll up and take little space. I gave 4 stars because I am waiting for the company to produce items in Canada

    Comfy sleep bottoms

    Wanted to try these for versatility for sleep or yoga in the mornings. Comfy material, a little long for the length (5'2"). Ordered oversized and the drawstring helps it stay up.
