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.

- WSWilliam S.Verified BuyerRated 1 out of 5 stars9/26/26Poor 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.
