The WWF water bottles are made of rugged ultra-lightweight aluminum. Each holds 16 ounces of cold liquid. Each bottle comes with a carabineer - perfect for clipping onto a backpack and showing off your commitment to conservation! They are reusable and will help save 1000s of unnecessary water bottles. They are dishwasher safe, however we recommend either hand washing or removing the carabineer before washing in the dishwasher to prevent it from losing its shine.

The aluminum water bottles exceed all existing standards and regulations for health and safety. In particular, independent laboratory tests found no detectable levels of BPA in these bottles.
