Safe by Design. Tested for Peace of Mind.

Because what touches your baby's skin matters.

At Smart Bottoms, we believe safer products begin with better materials — and the testing to back them up.

From independently tested waterproof fabrics to certified textiles and carefully selected components, every detail reflects our commitment to your child's safety.

Since 2010, we've believed parents deserve products they can feel good about, inside and out.

Independently Tested for PFAS

Waterproof protection. No unnecessary compromises.

You shouldn't have to choose between keeping leaks contained and feeling confident about the materials against your baby's skin.

Our diapers use a TPU waterproof layer to help prevent leaks without relying on intentionally added PFAS treatments.

But we don't stop at supplier promises.

We had our waterproof fabric independently tested by a third-party laboratory for total fluorine, an indicator of PFAS chemicals. The result? No detectable fluorine.

That's one more way we're working to give parents confidence in the products they choose for their little ones.

Certified Materials. Thoughtfully Chosen.

Soft on their skin. Held to high standards.

The fabrics and components in our products are selected with comfort, quality, and safety in mind.

We work with suppliers whose materials and textile processes carry recognized certifications, including OEKO-TEX STANDARD 100 and GOTS.

OEKO-TEX STANDARD 100

Our documented OEKO-TEX certifications include Product Class I — the strictest category, designed for babies and young children.

This means our raw materials and processes have been evaluated against rigorous requirements for harmful substances.

GOTS — Global Organic Textile Standard

We prioritize organic cotton and work with GOTS-certified textile sources. GOTS establishes requirements for organic fibers, chemical processing, and responsible textile production.

For us, choosing better fabrics isn't simply about softness. It's about being thoughtful about what goes into the products your family uses every day.

Safety Is in the Details.

Even the smallest components matter.

From the waterproof outer fabric to the snaps that keep our diapers securely in place, we believe every component deserves attention.

That's why we invest in independent testing to evaluate materials against applicable U.S. children's product safety requirements.

Our documented testing includes:

  • Lead: Our tested waterproof outer fabric and plastic snaps passed applicable lead safety requirements.
  • Phthalates: Our tested waterproof outer fabric passed applicable phthalate requirements, with none of the tested phthalates detected.
  • CPSIA: Our testing supports compliance with applicable chemical safety requirements under the Consumer Product Safety Improvement Act.

Because when it comes to your baby, the little things matter.

Made with Care. Made with Accountability.

Our commitment to responsible products extends beyond the materials themselves.

We partner with a manufacturing facility that participates in Sedex, a globally recognized platform focused on responsible business practices and supply chain transparency.

Sedex supports the evaluation and improvement of working conditions, workplace safety, environmental practices, and business ethics.

Because making products we feel proud of means caring about both the families who use them and the people who make them.
