About this item

• MOST ADVANCED STRAW LID: No other straw lid on the market can match our patented dual ball valve technology, which is LEAK-PROOF when closed, EFFORTLESS to drink from when open, and the Intelligent Venting automatically vents any built up pressure while moving from the closed to the open position. It’s so effortless that most people find they drink more water. The open air path makes it completely silent while drinking. | PATENTED DESIGN: Ever notice how other straw lids look so similar? Most are sourcing from the same few manufacturers who copied the design from Hydro Flask's old straw lid. With little to differentiate them, they're in a price war. That's good for your pocketbook, but does nothing to improve your hydration. We developed our straw lid from scratch in order to give you the best possible hydration experience. If you want to save a few dollars, buy theirs. If you want the best, get Paravalve. | EASY TO CLEAN: The removable spout makes it is easy to clean. Solid non-rubberized spout won't get chewed up or degrade. Top rack dishwasher safe. Includes 2 extra long straws and 1 straw cleaning brush: Straws are 260mm (10.24”), perfect for the very tall 48 oz Nalgene Silo bottle, and long enough for all Hydro Flask bottles. Straws must be cut to length for your bottle - simple instructions provided on package. Made from BPA FREE polypropylene. | ICE LASTS LONGER: Unlike most straw lids, ours is INSULATED to help maintain the temperature of your beverage and minimizing condensation which can soak your belongings. A vacuum insulated bottle deserves an insulated lid. Safe for liquids up to 140 degrees F. (60 degrees Celsius). | SOFT TOUCH RING HANDLE: Our minimalist Ring handle is made of unbreakable rubber which is unobtrusive and easy to carry. This is a pack of 2 paravalve straw lids, 2 cleaning brushes and 4 extra long straws. | MAINTENANCE: Because dirt can compromise the seal, we recommend periodically doing a deep clean of the lid by removing the spout and washing with warm soapy water. Full instructions in the User's Guide. If a leak develops, try deep cleaning and then flipping the water seal upside down. The seal design was upgraded in Nov. 2024 - See our store for replacement seals.
