This 750ml Tritan bottle, with a Capybara theme, from iDrink (reference ID2120G), is a reusable bottle made of transparent copolyester. Tritan is a BPA-free, transparent, and virtually unbreakable copolyester that does not retain odors or stains and is resistant to both heat and cold, making it dishwasher safe. This is the larger capacity version of the same capybara theme, also available in 500ml. It's a preferred option for fans of this rodent who need more volume than the 500ml version.
