What does squat proof mean, and how can you tell if leggings are squat proof before you wear them to the gym? This guide explains the squat test, what makes workout leggings opaque and flattering, and where to buy workout leggings that pass.

What does squat proof mean?

Squat proof leggings stay opaque when the fabric stretches, so nothing shows through during squats, lunges or yoga. It depends on fabric thickness, knit, color and fit.

How to do the squat test

  • Put the leggings on and stand in natural daylight in front of a mirror.
  • Turn around and do a deep squat, looking over your shoulder.
  • If you can see skin or underwear, the fabric is too thin or the size is too small.

What makes leggings squat proof?

  • Fabric weight: thicker, double knit fabric stays opaque.
  • Color: black, navy and darker shades hide more than pale colors.
  • Fit: leggings that are too small stretch thin. Size up if needed.
  • Texture: ribbed, scrunch and printed fabrics help hide sheerness.

Which gym leggings are most flattering?

High waisted leggings smooth the midsection, and scrunch butt leggings lift and shape. V waist styles also flatter from behind. Shop workout leggings.

Why are some workout leggings so expensive?

Premium brands charge for their name, marketing and specialty fabrics. Many affordable leggings use similar polyester and spandex blends. Compare fabric, thickness and fit rather than price alone.

What to wear with athletic leggings

Pair black athletic leggings with a matching sports bra, a cropped tank or an oversized tee. Darker shades like maroon pair well with black, white and grey.

See through leggings and how to avoid them

Leggings that are see through usually have thin fabric or stretch too much in a squat. Non transparent leggings use denser, double layered fabric. Check for no front seam leggings too, which avoid an unflattering line.

Best underwear for leggings

The best no show underwear for leggings is a seamless thong or seamless brief in a skin tone. Seamless underwear for leggings leaves no lines and is the best gym underwear. Shop seamless panties.

Sheer leggings and visible panty lines

Sheer yoga pants and the thinnest leggings are more likely to be see thru. To avoid VPL, or visible panty lines, wear seamless knickers or undergarment shorts under leggings. The best black leggings that aren't see through use thick, double knit fabric.

Squat test and no show underwear

Do a squat test before you buy: squat in bright light in front of a mirror. Squat proof leggings, also written squatproof, pass with no see through. Squat proof capris and patterned squat proof leggings use the same thick fabric.

The best no show underwear for working out is seamless and moisture wicking, so it does not ride up. No show cotton underwear is breathable for everyday wear, and active women's underwear or performance underwear is made for sweating.
