The Blender Bottle Sport Mixer is the best shaker bottle by design thus far! Improves upon the previous model in all ways possible. A few points that really make this bottle stand out above the competition are: Made of Tritan Plastic (won't retain odors, impact resistant) Contour shape/rubberized grip (fits nice and secure in the hand) Added sport loop (makes toting the bottle around a breeze) patented whisk shaker ball (breaks up clumps) BPA Free Dishwasher Safe
