ProStak® W3

BlenderBottle ProStak is the ultimate all-in-one solution for the serious athlete, making it one of the coolest protein shakers on the market. The bottle’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. 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. The ProStak system’s unique interlocking jars have individual lids, making it possible to carry supplements, snacks, and more -- with or without the bottle. Built around the BlenderBall wire whisk and unique Twist n’ Lock containers, the BlenderBottle ProStak lets you carry supplements, snacks, pills, and liquid -- all in the same bottle. Integrated with the StayOpen flip cap, the adjustable carry loop lets you hold more when your hands are full and provides a convenient place to attach keys while at the gym. Made from only the highest-quality materials, BlenderBottle brand shaker cups and containers are -- and always have been -- BPA and phthalate free.
