Simple. Powerful. Iconic. The Classic™ shaker revolutionized the industry in 2004 with its iconic design, leak-proof seal, and BlenderBall® wire whisk. Years later, it's still the best-selling shaker on the market. Why? Because it works. Perfectly Smooth. Say goodbye to lumpy protein shakes. Our powerful mixing system uses the BlenderBall® wire whisk—found only in BlenderBottle® brand shakers—to deliver smooth protein and nutrition shakes with ease. 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. Leak Proof Guarantee. Toss the bottle in your gym bag and don’t worry when it tips. With a snug twist of the screw-on 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.

BPA-free plastic — it is not manufactured with bisphenol A (BPA) or other bisphenol compounds, such as bisphenol S (BPS). Lockable No-Spill lid system. Impact-resistant — products can be used without fear of shattering. Tough — extending the useful life of water bottles and food containers, potentially reducing waste. Exceptional dishwasher durability — encouraging proper sanitation for greater plastic container safety. Lighter than glass even though it looks like it — making it easier to handle without the fear of breaking.
