Children's PJ Birthday Blue

The Children's PJ Birthday Blue is a party that never ends: cakes, presents and balloons in orange and teal on soft white.

A long-sleeved top with matching pants in our signature stretchy bamboo, cut with a little added length so the set grows with them. Made for playing, sleeping and lazy days.

Made from 95% bamboo and 5% elastane: naturally breathable, temperature-regulating and OEKO-TEX certified, gentle on delicate, eczema-prone skin.

The birthday photo outfit for the big kid, matching the baby Birthday Blue Zipster. 2 to 8 years.

What parents say
Across thousands of Zipster reviews, parents keep coming back to the softness, the quality that survives every wash, and prints kids actually want to wear.
