The Original Clean Bottle is how it all began. Revolutionizing the water bottle industry by using a removable top AND bottom for easy cleaning, the now famous bottle has been featured at the Tour de France and on ABC's Shark Tank. The screw-off bottom makes cleaning easy so you never have to deal with that funky moldy mess at the bottom of your bottle again! Silicone washers ensure a leak-proof seal. The Original holds 23 oz, is BPA-free and dishwasher-safe, and includes a limited lifetime warranty.
