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."

    Comfy

    Great for Ireland 2 week trip. There during heat wave and also in the south it was quite chilly in the mornings. Kept me comfortable in all weather and I didn’t wash them till I returned. My travel partner thought they were super cute too. Buying the long sleeve top next. My regular sleepwear I can only wear a couple days, so cuts down on laundry time and resources.

    Absolutely love this ultra fine sleep top & bottom I have bought! I also wear them as indoor clothes and they're just the most comfortable thing! Don't second guess purchasing those!
