Seamless Comfort

Check out our new PhD® Seamless Underwear for the ultimate in breathability and comfort.


New PhD Seamless Underwear


We have updated our PhD Seamless Underwear to be even better than before.  In addition to wool next-to-skin for the ultimate in temperature and moisture regulation, we have added a wide, chafe-free waistband, as well as engineered knit textures.  Gender specific thermal body mapping looked at where men sweat the most, and then we strategically knit the underwear to give you warmth and breathability, where you need it most.

Merino Boxers For Every Day and Every Adventure

Our crazy soft Merino boxer briefs are game for whatever comes your way, thanks to the benefits of Merino and thoughtful design. Made for movement, they help regulate body temperature, manage moisture and resist odors. When it comes to men’s underwear, what else do you really need?


New Men’s Merino 150 Boxers


When it comes to men’s underwear, extra durability is always a good thing. That’s why we make our new boxer briefs with Core Spun technology. We’ve wrapped ultra-fine Merino fibers around a nylon core for added strength and long-lasting wear while still keeping the comfort of Merino next to skin.
