This bottle includes a travel cap to minimize spillage when you are on the go. The high-grade nipple is extra soft, providing easier transition from breast-feeding to bottle feeding. A patented venting system reduces incidence of gas and spit up, allowing air to flow back into the bottle, in turn reducing the vacuum created while nursing. Bottle is free of Bisphenol-A, PVC phthalates, lead and nitrosamines. Top rack dishwasher safe.
