The Saalt Leakproof Seamless Thong handles light flow days on its own terms: no visible lines, no bulk, and no PFAS treatments in the fabric. A 4-way stretch body in 62% polyamide and 38% elastane moves with you, while bonded seams keep the silhouette clean under anything. The recycled polyester lining does the quiet work, absorbing the equivalent of one liner or two light tampons across up to 12 hours.

PFAS-free construction across all layers, so you know exactly what sits against your skin.
Recycled polyester lining reduces virgin material use without compromising absorbency or softness.
Mid-rise, bonded seams and 4-way stretch fabric eliminate panty lines under fitted clothing.
Light absorbency works as a standalone on low-flow days or as a backup to a cup or disc.
Machine washable design holds shape over repeated washes, extending the product's useful life.

If you want period underwear that disappears under your clothes while still doing its job reliably, this thong is a practical everyday addition to a low-waste period routine.
