The BlenderBottle Collegiate Classic 28-Ounce Shaker Bottle is ready for the game, with officially-licensed NCAA university team colors and logos. Featuring a patented mixing system—with a 316 surgical-grade stainless steel BlenderBall wire whisk (found only in BlenderBottle brand shaker cups) that moves freely inside the bottle to smooth out drink mixes and meal ingredients—it’s ideal for protein shakes, smoothies, fiber drinks, meal replacements, and Bloody Marys before the game! It’s also a handy kitchen tool for mixing pancake batter, scrambled eggs, and salad dressings. The wide mouth makes it easy to add scoops of powdered mixes, meal ingredients, and liquids, and embossed markings show both ounces and milliliters for easy measuring anywhere (note that markings on the 28-ounce capacity shaker cup only go up to 20 ounces). Bottle contents and liquids are securely contained thanks to a tightly threaded screw-on lid that creates a leakproof seal, and a flip cap that snaps securely shut for shaking and transportation. The convenient loop top makes it easy to carry the bottle and offers a place to attach car keys while at the gym. The BlenderBottle Collegiate Classic 28-Ounce Shaker Bottle can also be used as a water bottle; the ball can be left inside, as it will never rust, chip, or peel. BPA and phthalate-free, dishwasher safe. Manufacturer’s limited lifetime warranty.
