Do these really stay invisible under leggings?

Most owners say yes, thanks to the seamless edges and thin fabric. Very sheer or very tight garments can still show a faint outline.

Many owners recommend going one size up, since the fit runs small. If you are between sizes, take the larger one.

What are they made of?

A nylon and elastane blend with 28% elastane, which gives the stretch and smooth finish. They are machine washable at 30 degrees.

Three pairs, all in solid black in this listing.

They work well for low-profile everyday wear, especially under fitted clothes. For heavy daily use, thicker cotton briefs tend to last longer.

They offer more stretch than most budget seamless briefs and a softer feel, but the sizing is less forgiving and the fabric is thinner.
