Everyday Comfort and Performance.
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.

Softer Than Cotton

Softer Than Cotton

This wool isn’t like your typical itchy sweater. We only use superfine (16.5 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.

About our wool

  • Woolmark® certified Merino wool means you can expect the highest standards related to fiber content, performance, color fastness, and dimensional stability.

    Ok but not the most comfortable

    This underwear is ok, but it's thicker and wider than I expected, so not the most comfortable for me. I actually didn't realize it was Final Sale when purchasing. I buy underwear all the time at the Gap, Nordstrom, etc and you can try it on with other underwear on and return if it doesn't fit right. I find it misleading that Unbound doesn't mark Final Sale boldly before you purchase such an insanely expensive piece of underwear! I found out after the fact when I tried to return and read the fine print. Ah well, I kept it, it was fine, the fabric is good quality but it's not the most comfortable and it's really pricey. Had I thought to go read their FAQ fine print, I would not have chanced it.

    I like a merino thong but if the model with a 24" waist needs a medium

    There is no size my medium size body will actually fit. I am about the height of the model but with 31" waist and about 41" hips, if the model is 6" smaller all over I can't really imagine that even the XL will work, though I take a Medium in the other brand I wear. Who would wear a small if a 24" waist needs a medium?
