Unbound How To

Meticulously crafted for your comfort

Packing for any trip should start with the perfect base layer. When designing our Merino wool boxer briefs, we were uncompromising down to every last detail. That’s why the ultra-fine Merino wool and reinforced stitching found here is the exact same Merino wool and stitching we use to make our Merino wool T-shirts.  We then went the extra step of perfectly blending each Merino fiber with Nylon and Spandex for extra durability and a more snug fit. You’ll also find a tag-free, ultra-soft waistband that prevents rubbing and irritation – definitely a plus for long treks. This is Merino wool underwear designed to take you places.
