SodaStream dishwasher safe carbonating bottles are made from high-strength BPA-free plastic. Specifically made to handle the pressure of carbonation and high temperatures of the dishwasher, this bottle can now stand up to the heat from the sun, giving you sparkling water while on the go. The hermetically sealing cap not only keeps your fizz fresh, but unlike other popular brands, you can take a sip, re-seal, and sip fresh bubbles again later. Don’t forget to exchange your empty gas cylinder at Guest Services and save up to 50percent. Gender: unisex.
