Our Straw Cap is designed for one-hand operation and upright, spillproof sipping (no tipping needed). The Straw Cap is perfect for the treadmill or yoga class. The pivoting handle provides a great way to carry the bottle and stows out of the way while drinking. Wide-mouth access makes it easy to add ice cubes or fresh fruit. Our straws are made of medical-grade silicone (not plastic). Always BPA/BPS-free and dishwasher safe, all components are made in the U.S. or Europe.
