Squat-proof leggings and legging sets

Nobody wants to find out mid-squat that their leggings turn see-through. Every FOREVER6IX legging is opacity-checked before it goes live, and this edit gathers every style that includes one: the crossover flare legging plus our sculpt, brushed, ribbed and seamless legging sets.

Opacity isn't one-size-fits-all — it depends on your size, the colour and how much the fabric is stretched. That's why we recommend testing at home: put them on, stand in front of a mirror in bright daylight with your back to it, and squat deep. If you can see skin or underwear through the fabric, they aren't for you. Our full guide walks through the test step by step.

If a pair ever turns sheer, contact us within 30 days of delivery and we'll replace or refund it. Darker colours and brushed finishes are generally the safest bet for heavy lifting days.
