ZoLi bottles are made from polyethersulfone (PES) plastic which is free of harmful chemicals such as bisphenol-A. These bottles feature an integrated valve on the nipple that reduces air intake and nipple collapse. The unique valve works the same as other anti-colic bottles without the extra parts to wash and assemble.

• BPA & Phthalate free
