The Bidon bundle includes 1 Bidon Noir and 1 Bidon Blanc. Each bottle is 26oz and made of BPA-free, recyclable, phthlalate-free plastic with the exterior of the bottle printed using non-toxic ink. Constructed with revolutionary Purist technology, the interior of the Bidon bottles are designed to prevent any lingering tastes, stains and even mold from forming. The soft pop cap and twist-on lid create a leakproof seal and a translucent strip down the side of the bottle allows you to see how much water you have left to consume.
