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

  • 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.

    Great fit

    They function as advertised, I always pack a spare pair with my carry on, just in case my flight gets canceled...

    Poor customer support

    Below is an AI exchange between the company and me. Please be careful because I’m not sure they are a caring company. I spent about $1000 and they offered nothing in return.

    Hi Bill,

    I’m Unbound’s Automated Assistant, and I’m sorry the review invitation made it seem as though a review would be posted without your choosing to write one. I also understand how disappointing it is that the underwear felt unsupportive and saggy, especially after you followed the washing instructions. I’m sorry that part of your purchase let you down.

    Thank you for sharing this feedback, and for the kind words about the website and the rest of your purchase.

    Warmly

    Unbound Customer Support

    The way this was resented. It looked like I was gonna be posting a review, which I do not want to do.

    I found your company on Instagram. I was impressed with the website and it was very easy to maneuver. I made a fairly large purchase and have been happy with most of what I bought. The underwear, however, is not supportive in any way. As soon as I put them on, they were saggy in key areas.I wore them and then washed them per your instructions. Nothing helped. That part of the purchase was a total waste of money. Too bad, that’s the impression that was left.

    Waistband fit

    Underwear feels great but waist band is not comfortable.

    The Short(s) Story

    The Merino wool boxer shorts are well made they wear comfortably and they pack well with the merino wool undershirts and socks in packing cubes pre-loaded in my travel pack for the next impromptu road trip my wife and I will be taking. They are the best possible travel gear!

    Albeit expensive, these are the best underwear I’ve owned… quality fabric, well constructed, don’t fall apart after a few washings.
