  • These are the most comfortable boxers I've ever worn....I am already a long time wool underwear fan but these blow any brands I previously wore out of the water.

  • Perfect weight, excellent construction and fit, best merino boxers I've found (and I've tried them all). Highly recommend.

  • Wear resistant, breathable and can take 24 hours of flying and driving without smelling...Thanks for making a solid product!

  • Pricey, but they have got to be the most comfortable ones I have ever owned. The texture is just amazing and the elasticity is quite nice...hugs your body without feeling too constricting.

Why merino boxers?

Our boxers check all the boxes: durable, supportive pouch, fabric retention, legs that stay in place, and minimal seams.

Merino wool is naturally moisture wicking, temperature regulating, odor-resistant, and ultra-soft, making our boxers and boxer-briefs the perfect foundation for work, travel, or play.
