Meticulously crafted for your comfort
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. This ensures Merino wool resists unpleasant odors often experienced with other fibers.

Softer than cotton

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

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.

About our wool

  • Sustainably sourced from independent, cruelty-free wool farms.
  • Woolmark® certified Merino wool means you can expect the highest standards related to fiber content, performance, color fastness, and dimensional stability.
  • WRAP (Worldwide Responsible Accredited Production) certified production.
  • Tested to ensure our clothing stands up to the rigors of travel and continual use.

    Right size, right length, great feeling

    I was pleasantly surprised by these. I wasn't too sure wool was the right fabric for underwear. My concerns were unfounded, they are super comfortable and fresh.

    Great!

    Super comfortable, great fit, odor free, easy wash, quick dry, stands up to many multiple machine washes. Merino is the best against the skin. I have worn Unbound Merino boxers for about four years and I love all my pairs.

    excellent briefs

    Comfort is king. Unbound Merino boxers are soft and odor free. Not that I have, but I certainly could wear them for multiple days. It is clear that these were designed to fit and tested, rather than just cutting out a pattern on a mannequin. Another winner!
