• The new and improved Classic™ shaker gives our tried-and-true best-selling bottle an impressive overhaul with modern design elements and pro-level performance features.

Perfectly Smooth.

• Say goodbye to lumpy protein shakes. Our patented mixing system uses the BlenderBall® wire whisk—found only in BlenderBottle® brand shakers—to deliver smooth protein and nutrition shakes with ease.

Spoutguard™.

• The Classic™ shaker sports an updated lid featuring a wider carry loop, ergonomic flip cap, and SpoutGuard™ to keep dirty gym fingers off the drinking surface. Our leak proof guarantee means you can toss the bottle in your gym bag and not worry when it tips. 

Rounded Base.

• Forgot to add liquid first? No sweat. The rounded base allows the BlenderBall® whisk to mix every last bit of powder.

• 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.

BlenderBottle classic shaker cups sport our updated lid, featuring a wider carry loop, SpoutGuard protection to keep dirty gym fingers at bay, and a more ergonomic flip cap.
