ErgoPouch Brand Rompers are the sleep essential designed to be worn under your baby's Swaddle or Sleep Sack. Made from a deliciously soft, stretchy organic jersey cotton, Rompers can be worn as either the base layer (closest layer to baby's skin), a mid layer with a singlet or bodysuit underneath, or as daywear too! The unique 3-way zip system has been designed for performance during sleep. By locating the zips down the body's midline, our Rompers can help prevent overnight nappy leaks by holding the nappy in place, and prevent the romper from twisting. The zip system also makes for easy nappy changes and dressing. Foldover hand and foot cuffs help retain warmth during sleep, and also protect little nails from scratching skin. 95% Organic Cotton / 5% Elastane Made from Global Organic Textile Standard (GOTS) certified organic cotton that is non-toxic and gentle on irritable skin.
