Lets start with the obvious. Wool is warm!

It gets better. It's soft, luxuriously soft. The smaller the fiber diameter, the softer the feel. Ours are 18½ microns on average. Teeny Tiny.

Then you add wool's amazing ability to not overheat when it gets hot. Think of it as a next-to-skin micro climate regulator.

It's odor free, naturally anti-microbial. When you're hot enough to sweat, don't worry, wool's remarkable chemistry (lanolin) stops the stink before it starts.

It's not combustible, so it resists burning.

It's easy to care for. Machine wash warm or cold, then tumble dry or hang.


And for the minority with sensitive skin, our 2-ply Merino Base Air comes with a polyester lining, yielding more insulation and faster wicking. The polyester is soft against even the most sensitive skin, and is hydrophobic to wick sweat away fast. The Merino outer layer adds the paradoxical climate control properties of all-natural wool; it's warm when it's cold, even when wet, and cool when it's not.


  • Relaxed fit (we recommend sizing down 1 size)
  • Flat seams
  • 2-ply construction: Polyester and Merino
  • Odor Free - naturally anti-microbial
  • Easy to care for
