Do these run true to size?

No. The sizing is Asian sizing, which runs one to two sizes smaller than US and EU sizes. If you are between sizes, choose the larger one.

What are they made of?

They are a knitted polyester blend, roughly 81 to 90 percent polyester, with the rest stretch fiber. The fabric is soft but less breathable than nylon-based leggings.

Are they squat-proof?

The knit is fairly opaque in dark colors, but lighter shades can show through when stretched. Dark colors are the safer choice for heavy training.

What is the inseam or length?

Length runs about 91 cm in S up to 94 cm in XL, measured with a 2 to 3 cm tolerance. Taller wearers may find them short.

Can I wear them outside the gym?

Yes. The slim, seamless look works for everyday athleisure, though the scrunch back seam is sporty rather than dressy.

Our take on the Hollow Seamless Slim Yoga Sweatpants

These are seamless knit yoga pants made mostly of polyester, cut slim through the leg with a wide elastic waistband and a scrunch-style seam detail at the back. The seamless construction reduces chafing, and the high-stretch knit moves with you through yoga, pilates and gym sessions. They are a budget alternative to branded seamless leggings, but the sizing runs small and the fabric is thinner than premium seamless styles. Best for shoppers who want a soft, stretchy everyday legging and are willing to size up.
