Why Primal Play

Four things we changed

The waistband

Most kids' underwear uses a wide elastic band, and a wide band has to squeeze to stay up. Most brands encase that band in fabric. We encase soft string elastic in narrow stitching instead, so there is less of it against skin to begin with. It holds without squeezing and sits flat enough to disappear under clothes. It is patent-pending.

The seams

Flat-lock seams lie smooth against skin instead of forming the raised ridge a standard seam creates.

The fabric

90% modal, 10% spandex, knitted to 185gsm. Modal has a smoother fiber surface than cotton and holds its shape through repeated hot washes.

The tags

There are none inside. Nothing printed, nothing woven, nothing to scratch.

Tested, not assumed

Every style is tested by a CPSC-accepted laboratory for lead content, phthalates, and flammability. We keep the report and the certificate on file.
