Why We Built This

Baselayers are essential, and the Liso is our go-to.

Why It's Different

The Liso’s fabric blend combines spandex and sustainably minded recycled polyester to keep moisture at bay.

About This Product


For those who won’t let teeth-chattering temps get in the way of their time outside, our Liso Baselayer Bottom is where your cold-weather layering begins. The Liso’s stretchy, recycled polyester fabric—which features a flat face for smooth layering, and a brushed backer for added next-to-skin softness—manages moisture during energetic pursuits and dries in a flash to keep you comfortable. We also added Polygiene® odor-control technology that’s embedded in the fabric, so you can wear it longer and wash it less.


  • Stretchy, moisture-wicking blend of recycled polyester and spandex
  • Polygiene® odor-control technology embedded in the fabric

Why You'll Love It

Polygiene® Odor-Control Technology

If you’re sick of washing your clothes with every other wear, these bottoms are for you. Embedded with Polygiene® odor-control technology, they keeps smelling fresh even after a long day on the slopes or trails.

Smoother than Smooth

We call it Liso for a reason. These buttery bottoms are perfect for seamless layering.

Simplicity Is Best

A great baselayer is simple with a few deliberate finishing touches, like the Liso’s odor-control technology and moisture-wicking fabric blend.
