Everything else is just a shaker cup. The BlenderBottle Classic revolutionized the industry back in 2004 with its leak-proof seal, iconic design, and the BlenderBall(r) wire whisk. Now, years later, it's still the best-selling shaker on the market. Why? Because it works.

Say "goodbye" to lumpy protein shakes and "hello" to smooth, great-tasting drinks. Our patented mixing system uses the BlenderBall® wire whisk-found only in BlenderBottle® brand shaker cups-to mix even the thickest ingredients as you shake.

Clip It, Loop It, Hang It: Integrated with the StayOpen™ flip cap, the adjustable carry loop lets you hold more when your hands are full and offers a convenient place to attach keys while at the gym.

100% Leak Proof: The Classic's screw-on lid and secure flip cap keep your gym bag and car seat dry. With a snug twist of the lid and the assuring "snap" of the flip cap, you're ready to roll.

Worry Free: Made from only the highest-quality materials, BlenderBottle® brand shaker cups are-and always have been-BPA and Phthalate free.

Dishwasher safe.
