The Specialized Little Big Mouth 21oz Water Bottle takes the innovative design of its best-selling predecessor and refines it for an even more convenient, leak-proof experience. Featuring a wide Big Mouth screw top, it's perfect for adding ice cubes or your favorite hydration powder. The bottle boasts a water flow rate up to 50% greater than leading competitors, ensuring quick hydration when you need it most. Its flexible, ergonomic shape ensures a secure fit in your cage and offers a comfortable grip in hand.

The MoFlo cap, which retains its excellent flow mechanism, has been updated for easier cleaning with a flush top and improved grip, all while keeping the bottle 100% leak-free. For added versatility, the Little Big Mouth bottle is now even easier to hold and more flexible than before, offering a design that suits your active lifestyle.

Made from BPA-free, FDA-approved food-grade plastic and printed with non-solvent-based, UV-cured ink, this bottle is as durable as it is functional.
