The Extend Nutrition Leak Proof Protein Shaker Bottle 28oz. makes it easy to maintain your nutrition and hydration on-the-run. Featuring a surgical-grade stainless steel wire whisk ball that moves freely inside the bottle to smooth out drink mixes, supplemental powders and add-in ingredients—it’s perfect for Extend protein shakes, smoothies and meal replacements.  The wide mouth makes it easy to add scoops of powdered mixes, add-in 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 leak proof seal, and a flip cap that snaps securely shut for shaking and no-drip transportation. BPA and phthalate-free, dishwasher safe.
