Nature's Miracle Fabric

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

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 feel that’s lighter and more plush than your average Merino or cotton. And unlike most clothes, it'll also maintain its form over time and won’t get ruined after a wash.

Easy care

Easy care

You won’t have to wash these trunks much at all. However, when it comes time for a refresh, simply add it to your load on the cool temperature setting and then lay flat to dry.

    Finally Some Merino Trunks!

    Same great quality as the boxer briefs, just shorter so they don't show under shorts. Back rise feels a bit lower, but in general, get eth same size as you have for the boxers. Will buy again.

    Best Merino Wool Trunks

    Tried 4 different brands looking for 100% Merino wool trunk and these are hands down my favorites. Bought one pair. Tried them. Bought four more pairs the next day. Love them. Good for work, good for lounging, good for sports.

    Outstanding Briefs!

    Unbound Merino Wool Trunks exceed the standard for great underwear. Like all merino apparel, they are comfortable, but these trunks excel in being moisture-wicking and cool with an exquisite fit.
