Our plastic bottles are BPA-free and truly unique. We were the first to introduce this bottle shape which fits perfectly in your hand. The good news is that they won'’t last forever because they are made of a recyclable plastic (LdPE no. 4). The 7oz and 10oz sizes are compatible with all past and present FuelBelt designs. Our new colors for 2010 were coordinated to accessorize the H2O and Helium collections. Mix and match color bottles with your belt to create your own unique combination
