Nature’s miracle fabric

Nature’s miracle fabric

Every Merino wool fiber has a waxy coating called Lanolin, which helps wick moisture away from your body, and act as a safeguard against odor-causing bacteria. This is what allows our Merino to stay breathable and dry while smelling and feeling fresh, no matter what you put it through.

Softer than cotton

Softer than cotton

This wool isn’t like your typical itchy sweater. We only use superfine Merino wool, resulting in a luxuriously silky soft feel that’s lighter and more plush than your average Merino or cotton. And unlike most clothes, it'll also maintain its form over time and won’t get ruined after a wash.

Easy care

Easy care

Your shorts will rarely need a wash. When it’s time for a refresh, simply add them to your load at a normal or cool temperature setting and 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."

    Great fit

    The shorts fit well and are a great neutral colour and go well with my new tee shirts.

    Avg at Best

    I tried the Unbound Merion Flex Shorts and they’re OK overall, but honestly not on par with some of Unbound’s other products. The fit and flexibility are decent, but the cost component and the fact they’re made in China takes away from the premium feel the brand usually delivers. At this price point, I expected more — they feel very pricey for what they are. If you’re already a fan of Unbound, these might work for casual wear, but I wouldn’t call them a standout piece compared to the rest of the lineup.

    Great shorts for Pilates and yoga

    Great shorts for Great shorts for Pilates, yoga and 'activities'. Not so much for general walking or wearing about as there's no back pocket or loops for a belt.

    They are very comfortable, flexible and stretchy though.

    Tight for athletic legs

    I ordered a large. I’m 6’3” 212 lbs , athletic build . These are too tight in my opinion annd compared to a sized 34 Lululemon ABC short . I like to wear my shorts at mid thigh and find The elastic component of the shorts seems to ridgid causing the shorts to ride up to high when sitting or making bigger steps
