PROTEIN SHAKER BOTTLE WITH MIXING BALL: Food-grade 304 (18/8) stainless steel shaker built for protein powder, pre workout, electrolytes, and shakes – the stainless mixing ball breaks up clumps so your shake is smooth by the time you hit the gym floor.
INSULATED STAINLESS STEEL: Double wall insulation helps keep pre workout and protein shakes cold from the time you leave home through the last set – plus the insulated stainless steel prevents the shaker from sweating all over your gym bag.
