This 1000ml Tritan bottle, in lilac/green, from iDrink, reference ID2122, 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, and is dishwasher safe. The contrast between lilac and green creates a softer two-tone effect than the orange combination in the same range. It is a preferred option for those who prefer a more discreet two-tone in this 1000ml capacity.
