What Makes Activewear Fabric Squat-Proof?

Squat-proof activewear depends on fabric coverage under stretch and a garment fit that does not overstretch the material.

Knit density, yarn, color, weight, and surface finish can all affect visibility. A heavy fabric or dark color alone does not guarantee coverage.

Evaluate the finished leggings in representative sizes during deep movement under consistent lighting, and agree on a repeatable opacity assessment before making a squat-proof product claim.
