The BlenderBottle Strada Tritan Shaker Bottle with Locking Lid features an easy-open/easy-close push-button flip cap with a sliding lock to prevent accidental opening. At 24-ounces (measurement markings to 16 ounces), the sleek and durable shaker cup has plenty of room to mix protein powders, supplements, or meal replacement smoothies, using the BlenderBall Whisk, which delivers smooth shakes in seconds without batteries, cords, or hassle. It can also be used as a water bottle. Screw-on lid is leakproof, and the wide mouth accommodates oversized scoops and makes for easy cleanup; a rounded base ensures thorough mixing. The flexible, ergonomic carry loop provides a comfortable hold, and a place to attach keys or hook the bottle to a gym bag. The BlenderBottle Strada is made from BPA- and phthalate-free, stain and odor-resistant durable Eastman Tritan plastic. Top-rack dishwasher safe. Manufacturer’s limited lifetime warranty.
