Hegen Feeding Bottles prevent colic with air venting that bypasses milk, preserving nutrients and reducing air intake to prevent tummy upsets. The off-centre, super-soft teats allow upright feeding at a natural 20-degree tilt, minimising back-flow and lowering the risk of mid-ear complications. Made from FDA-compliant PPSU, a tough, high-temperature-resistant material used in medical appliances, Hegen bottles handle -20°C to 180°C, allowing seamless freezing, heating, and feeding.
