After last year’s foofaraw about the health risks of BPA (bisphenol-A), two companies, Polar and CamelBak, have come out with new insulated water bottles designed for cyclists. Insulated water bottles keep water cooler twice as long as standard plastic bottles.
Polar’s water bottle is made of LDPE, low density polyethylene, plastic #4, and does not contain BPA or Phthalates. It’s also environmentally friendly—plastic #4 is recyclable. CamelBak’s answer to the Polar bottle, the Podium Chill, is also BPA and phthalate free but the company website doesn’t say what kind of plastic it’s made of.
