How We Test Our Leggings for Squat-Proofing

Most brands print "squat-proof" on a swing tag and never test it. Ours goes through a specific process before a fabric batch is approved. Every roll of fabric is cut, sewn into a sample, and stretched to full squat depth over a light box — the same conditions that expose thinning fabric under a gym mirror or a phone camera. We check from directly behind, at the angle a training partner or a mirror actually sees, not a flat lay on a table. If light passes through and skin tone shows, the batch is rejected before it reaches production, regardless of how the fabric performs in other tests like colour-fastness or stretch recovery. This isn't a one-off pre-launch check either — batches are periodically re-tested through the production run, because fabric mills can drift on density between orders even when the spec sheet stays the same. It's a slower, more expensive way to source fabric than trusting a supplier's spec sheet. It's also the only way we're comfortable putting "squat-proof" on a product page.
