ProStak® K6

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 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. Say 'goodbye' to lumpy protein shakes and 'hello' to smooth, great-tasting drinks. Made from only the highest-quality materials, BlenderBottle brand shaker cups and containers are -- and always have been -- BPA and phthalate free. 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. 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 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.
