    Merino Wool + Tencel

    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. Our Merino wool is blended with Tencel for added breathability, durability, and an extra soft feel.

    Cotton Can’t Compete.

    Comfy, cozy, super soft & breathable. This wool isn’t your typical itchy sweater wool. We only use superfine Merino wool, blended with all natural Tencel, resulting in a luxuriously soft yet totally breathable feel that you’ll notice as soon as you try them on.

    READY TO GO WRINKLE RESISTANCE

    READY TO GO WRINKLE RESISTANCE

    A Merino wool fiber resembles a tight coiled spring, also called a crimp. Pull it and it will recoil back into shape every single time. It means even after a day on the trail, these will still look good enough for a night on the patio.
    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. It makes our sweatpants perfect for humid climates and active adventuring.

    Perfect for Travel

    • You'll pack Lighter
      With clothing that doesn't smell after every use, you can pack less, allowing you to ditch the suitcase and travel with just a small backpack.
    • You’ll Save Money
      These days, most airlines are going to charge you for anything other than a carry-on. Start packing lighter and doing less laundry, and save your money for the real experiences.
    • You’ll Save Time
      Never check luggage or worry about airports losing your stuff. With fewer but better clothes you’ll blaze through airports like a seasoned pro.

    Easy Care

    You won’t have to wash these pants 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!
