The thong you reach for every day, just with built-in protection you'll actually forget is there. No bulk. No tradeoffs. No tampons. Just soft, breathable TENCEL™ Modal against your skin, and a 3-layer gusset doing quiet, powerful work so you don't have to think about it.


Light to moderate days? Handled. White pants? Go for it.

Made from natural TENCEL™ Modal and toxin-free materials, this thong is soft, breathable, and designed so the protection disappears into the fabric, not into your day. Each pair is washable and reusable for 300+ wears, saving you money, reducing waste, and eliminating those constant monthly restocks.

Because what touches your body matters. Proudly made in Los Angeles.

3-Layer Leakproof Gusset Technology

1. Quick-Dry Top Layer (Against the Skin)
Soft, breathable, and engineered for high-performance wicking. Pulls moisture away instantly for a cool, dry feel all day.
2. Absorbent Core Layer (The Powerhouse)
Our antimicrobial absorbent layer soaks moisture up to 20× faster than cotton, bamboo, or hemp. Powered by SILVADUR™ technology, it reduces odor-causing bacteria by 99%+  without irritating or harming your skin, and becomes more absorbent over time.
3. Waterproof Bottom Layer (The Barrier)
Flexible, breathable, and completely toxin-free. This eco-engineered layer uses a solvent-free bonding process that emits no VOCs or harmful chemicals, while keeping leaks fully contained.
