Love these boxer briefs!!
These boxer briefs are by far the most comfortable that I have ever worn. What I love is that the material is 100% merino wool, unlike so many other brands that use hormone-disrupting chemicals in their fabrics forever. I will be replacing all of my boxer briefs with these Merino Wool Boxer Briefs.

Fits great
When I asked my husband how these felt after a day of wear, he said he didn't even notice them. No higher praise for underwear!

Meticulously crafted for your comfort

Odor-resistant and antibacterial.

Less washing with antibacterial clothing that stays dry, clean and fresh.

Dries really fast, keeping you comfortable.

Performs better than cotton and synthetics.

Tag-free band to prevent rubbing.

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. This ensures Merino wool resists unpleasant odors often experienced with other fibers.

Softer than cotton

This wool isn’t like your typical itchy sweater. We only use superfine (18.5 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

You won’t have to wash these briefs 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."
