Not all organic cotton underwear is made the same.

Most brands choose the lightest organic cotton that meets the label. We chose a heavier-weight GOTS organic cotton knit — because the clothing kids wear most should feel exceptional every day.

The difference you can feel

Most organic underwear brands focus on "100% Organic" first and comfort second.

Treehouse starts with fabric quality — using thicker, higher-weight organic cotton that parents immediately notice feels softer, stronger, and simply better.

Frequently Asked Questions

HOW DO TREEHOUSE UNDERWEAR FIT?

Based on feedback from hundreds of families:

  • Girls: we recommend sizing down if your child is between sizes.
  • Boys: if your child is between sizes, size up for the best fit.

Our cuts are designed for comfortable coverage without twisting or riding up. If you’re unsure, sizing up usually allows for longer wear.

WHAT IS YOUR RETURN POLICY?

We want you to feel confident trying Treehouse.
After trying on over underwear, if the fit isn’t right, you can request a free return label. Just make sure the original tags remain attached.
You can start a return anytime here

WHAT KIND OF COTTON DO YOU USE?

Treehouse underwear is made from 100% GOTS-certified organic cotton.
But certification alone doesn’t determine comfort. We chose a heavier-weight organic cotton knit, which feels softer, more substantial, and holds its shape better over time than many lightweight cotton fabrics.

Because underwear sits directly against your child’s skin all day, fabric quality matters.

WHERE ARE TREEHOUSE UNDERWEAR MADE?

Treehouse underwear is produced in Noida, near Delhi, India, with our GOTS-certified manufacturing partner.
The facility meets strict environmental and social standards, and workers are paid living wages under audited labor practices.
