      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.

      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!

      Good quality but have one suggestion

      It’s not easily to distinguish front from back and you actually have to look for the little white tag (at least I do). It’d be so much easier if there is a brand label on front (or something similar). Otherwise all great!

      My Search Is Over

      I travel loads for work and play. I'm a single bag, minimalist packer. Over the past 5 years, I've tried five our six Merino brands, and these are hands down the clear winner for me. They are comfy, and durable. The other brands, all developed holes after a relatively short period of time. I travel with 3 pair, hand wash and I'm good to go.

      Outstanding

      I’ve been super pleased with this new version of the boxer briefs. Hopefully the nylon-spandex addition will have made them much more hard-wearing than the first version back in 2017.
