Designed to address the growing concern of toxic chemicals leaching from consumer products, this bottle is made of recyclable polypropylene and is free of BPA, phthalates, PVC, lead, nitrosamines, melamine and biologically toxic chemicals. It has a travel cap and a venting system to help reduce colic. High-grade silicon nipples are used, available in seven styles and flow designs, to ease transition from breastfeeding to bottle feeding. The bottle is dishwasher safe. "In addition to being safe, our products are full of functional benefits and are highly sustainable," Kevin Brodwick, founder of thinkbaby and thinksport, told TDmonthly. Launch date: 2006.
