High-stretch mesh maximizes airflow, draws sweat away, and dries rapidly to support cool, dry comfort during hot yoga, training, outdoor work, hiking, and humid travel.

Secure Active Fit

Flexible 3D contouring, reinforced thigh bands, and an elastic-free waist adapt to pear, apple, and peach shapes without rolling or shifting. Includes a 100% cotton-lined antibacterial gusset and is machine washable.
