Category: Period Underwear

The Saalt Leakproof Mesh Thong delivers real protection without the bulk, built for light flow days when you want coverage that disappears under clothing. Sheer mesh fabric and a soft, stretchy mid-rise waistband work together to eliminate visible panty lines while the gusset handles what a liner would, quietly and reliably.

  • Light absorbency replaces one or more liners or two or more light tampons, making it a practical standalone for light flow, spotting, or discharge days.
  • Body fabric uses 80% recycled polyester with elastane for a breathable, second-skin fit that moves without bunching or shifting.
  • PFAS-free construction means no fluorinated chemical treatments in the layers sitting closest to your skin.
  • Mid-rise cut with a seamless mesh silhouette stays invisible under fitted clothing, from leggings to tailored trousers.
  • Machine washable and built for repeat use, reducing the single-use waste of disposable liners over time.

Wear it as your primary protection on lighter days or as a confident backup alongside a cup or tampon. The Leakproof Mesh Thong fits into a real routine without asking you to think twice about it.

Victoria Q. ★★★★★

I finally tried these out on a light day and the mesh fabric truly is invisible under my tightest yoga pants. I actually forgot I was wearing it, which never happens with period underwear.

Abigail ★★★★★

I finally don't have to worry about panty lines on light days—the sheer mesh really disappears under my tight jeans. The stretchy waistband stays put without digging in, which is a nice bonus.

Victoria L. ★★★★★

It’s nice to have period underwear that actually stays put and doesn’t feel like a diaper. The stretchy fabric moves with me without riding up at all. Feels secure for a light day.
