Frequently Asked
What is the best fabric for yoga and Pilates pants?+
There is no universal winner. Nylon- or polyester-elastane blends are common, but knit construction, recovery, opacity, surface, fit, and intended use predict performance better than fiber percentages alone.
How should you test leggings before keeping them?+
Use the exact size and color under strong light, then squat, hinge, lunge, sit, and check recovery. Confirm that the waistband stays stable, seams do not restrict movement, and hems suit the activity.
