Preemie / NICU Sleeveless Bodysuit – Micro Preemie to Early Baby
Designed for premature, preemie and low-birth-weight babies, the ZB Preemie / NICU Sleeveless Bodysuit combines a lightweight sleeveless design with tiny-baby sizing, soft 100% cotton and easy-access Velcro closures.
Unlike standard newborn clothing, this bodysuit is available in dedicated ZB sizes from Micro Preemie through Early Baby, helping parents choose a fit based on their baby's current weight and body length rather than age alone.
The sleeveless construction keeps coverage light for warm weather and indoor environments, while the soft cotton fabric allows comfortable everyday movement. Easy-access openings and Velcro closures are designed to make dressing, diaper changes and frequent care simpler without unnecessary layers or complicated fastenings.
