    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.
    Meticulously crafted for your comfort

    Nature's Miracle Fabric

    Every Merino wool fiber has a waxy coating called Lanolin, which helps wick moisture away from your body, and act as a safeguard against odor-causing bacteria. This is what allows our Merino to stay breathable and dry while smelling and feeling fresh, no matter what you put it through.

    Softer than Cotton

    This wool isn’t like your typical itchy sweater. We only use superfine (17.5 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.
    Natural airflow

    Natural airflow

    With Merino, your body heat can pass through the space between our woven superfine fibers, regulating your body temperature and keeping you cool & comfortable.
    ENHANCED DURABILITY

    ENHANCED DURABILITY

    When designing our briefs, we went the extra step of blending each Merino fiber with Nylon and Spandex for extra durability and stretch. You'll also find a tag-free, ultra-soft waistband that prevents irritation--definitely a plus for long treks. This is Merino wool underwear designed to take you places.
    Perfect for Travel

    Perfect for Travel

    With underwear that don’t smell after every use, you’ll only need to pack just a few on your next trip. Wear one pair while you let the other two air out. They’ll be good as new the following day. Should one need a proper wash, a quick hand wash and air-dry and you’re good to go.
    Designed with Versatility in Mind

    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.

    Rocking my Unbound Merino V-neck… having an every-day outfit I feel good in reduces cognitive fatigue and allows me to put all my focus on the people I love and the things I want to accomplish.

    There was no way I could have possibly traveled as lightly as I did without my Unbound Merino gear. I still can’t believe that these clothes feel so good and really don’t smell after so many days worn consecutively; it’s just awesome.

    Unbound Merino performs as promised, and has totally simplified how I pack when I travel the world. The shirts are AWESOME and the underwear feels like having your balls cradled by the hands of angels.

    I’ve worn the Unbound Merino t-shirt for most of the 18 days I’ve been travelling through Hong Kong and Thailand. Super impressed that this shirt does as promised, it doesn’t smell at all despite no washing for 18 days!

    The best underwear. Ever.

    This is simply the best made, most comfortable, easiest to clean & maintain, least prone-to-getting-stinky underwear you will ever buy. Definitely worth having a week’s supply. Highly recommended.

    Great Underwear!

    I utilized this underwear on a recent trip to Peru. The garments were very comfortable and super durable. I would highly recommend them as essential travel wear!
