PFAS-Free*

We engineer our leakproof layers without PFAS or other unnecessary chemical treatments—prioritizing material safety, long-term wear, and peace of mind against your skin.

We use stitched construction, not tape or glue (bonding), to improve durability, reduce stiffness, and withstand 100+ wash and dry cycles. Bonded seams can break down and stretch out in the wash.

Our products are made with OEKO-TEX® certified fabrics free from harmful substances, for breathable comfort, reduced irritation, and safer long-term skin contact.
