Supplements, snacks, pills, and liquid—all in the same bottle. Featuring the BlenderBall® wire whisk and unique Twist n’ Lock™ containers, the BlenderBottle® ProStak® is the all-in-one solution for the serious athlete.
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.
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.
The Prostak’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.
Made from only the highest-quality materials, BlenderBottle® brand shaker cups are—and always have been—BPA and Phthalate free.
The ProStak’s unique interlocking jars have individual lids, making it possible to carry supplements, snacks, and more—with or without the bottle.
