BACK IN... BORDEAUX!

Maximum breathability for high-output days.

Standard base layers trap too much heat when you're working hard. You need something that wicks moisture and allows serious airflow without adding weight.

The Mesh Base Layer Bottoms are built with MESH DUAL SURFACE™ Precision Blended Wool - an ultralight construction that prioritizes breathability and moisture management over insulation. These are for warm-weather pursuits or cold-weather efforts where you're generating enough heat that traditional base layers would drown you in sweat.

What you're getting:

• Mesh construction maximizes airflow and reduces weight
• DUAL SURFACE™ technology wicks moisture away from skin
• Ultralight design for year-round high-output activities
• Natural odor resistance through extended wear
• Athletic fit stays in place during movement

Important: These are NOT squat-proof. The mesh construction prioritizes performance over opacity. Wear them under shorts, skirts, or as a true base layer under pants.

Use these when breathability matters more than coverage. Trail running in summer. Ski touring when you're climbing hard. Bike commutes. Any activity where standard base layers would overheat you.

Fit: Athletic
Made in the USA.
