The Blender Shaker Bottle is easy to maintain proper nutrition and hydration on-the-go. Featuring a patented mixing system—that moves freely inside the bottle to smooth out drink mixes and meal ingredients—it’s ideal for protein shakes, smoothies, fiber drinks, and meal replacements. 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.
