SmartShake v2 20 oz Jay Cutler - Limited Gold Edition with Jays signature in gold. This design was developed together with defending 4 time Mr. Olympia winner Jay Cutler. The SmartShake v2 20 oz has three separate compartments in which you easily store several servings of nutritional supplements. For example: Protein, Creatine, Vitamins, Capsules, Pre- & Post-Workout Products. The benefit with SmartShake is the ability to carry around three protein shakes or a mixture of protein shakes, pre/post workout drinks all in one unit. It's much more convenient than carrying the alternative: Ttree individual shakers, or worse, three tubs of your supplements. With SmartShake you can store anything you like all in one convenient unit.
