Our best-selling bottle, the Little Big Mouth 21oz Bottle takes a revolutionary design and shrinks it down a bit. It's conveniently shaped and absolutely leak-proof. It has a tight-sealing Big Mouth screw top that's ultra-wide for adding things like ice or your hydration powder of choice. This piece also provides an incredible level of water flow that's up to 50% greater than the competition. Meanwhile, we gave the bottle a flexible, ergonomic design that grips to cages and fits easily in the hand, while the bottle's construction is made from BPA-free plastic that's 100% FDA food-grade approved.

- Also available in 24oz Big Mouth option
- BPA-free plastic made from 100% FDA food-grade materials and printed with non-solvent base (UV cured), CPSC-approved ink and materials
