This is Specialized best-selling bottle, the 2nd Generation 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.
This water bottle is awesome! I use it every time I’m on the Peloton exercise bike along with my ZYM tablets. It’s the perfect size for the bottle holder and easy to grab and use quick. I grabbed an extra one so I can use one in each bottle holder for longer endurance rides. One for electrolytes and one for regular water, works great!
