The BlenderBottle Just for Fun Classic V2 28-Ounce Shaker Cup makes it easy to keep a sense of humor at the gym, with food-inspired designs that spark conversation. With an upgraded modern design, and feature updates-including a rounded base and SpoutGuard-the Classic V2 makes it easy to maintain proper nutrition on-the-go. The patented mixing system-with a 316 surgical-grade stainless steel BlenderBall wire whisk that moves inside the bottle to smooth out mixes-makes it ideal for protein shakes, smoothies, fiber drinks, and meal replacements. A wide mouth makes it easy to add ingredients, and the rounded base ensures thorough mixing and easy cleanup. Bottle contents and liquids are contained by a screw-on lid that creates a leakproof seal, and a flip cap that snaps securely shut for shaking and transportation (fits in most cupholders). A SpoutGuard makes it possible to open the flip top without touching the drinking spout, keeping the mouthpiece clean. Embossed markings show ounces and milliliters for easy measuring (note: measurements only go to 22 ounces). The BlenderBottle Just for Fun Classic V2 Shaker Cup can also be used as a water bottle. BPA- and phthalate-free. Top-rack dishwasher safe. Manufacturer?s limited lifetime warranty.
