Squat-Proof Leggings

Squat-proof is a claim most leggings can't back up. A thirty-second test that tells you the truth before you're in a class.
Every activewear brand uses the term 'squat-proof'. Most of them shouldn't. A squat is a brutal test of fabric: the knit is pulled thin across the thighs, and light passes through whatever doesn't have enough density to block it.
The thirty-second test
Fold forward as if reaching for your toes, in front of a bright window or under studio lighting. Have someone look at the fabric across the back of the thighs. If you can see the colour or texture of your skin, the legging is not squat-proof, regardless of the label.
What makes a legging squat-proof
Density. A knit around 230–260 gsm is usually enough. Below 200 gsm, most fabrics will thin under stretch, no matter how expensive the brand.
