New and Improved Design. New Manufacturing Process. Fully injection molded in the USA for a clean, crisp, precise finished product. Helimix uses an innovative patented design to ensure every athlete's sports drink mixes smooth. The shape of the cup itself does the mixing and it works way better than you think. Forget the days of cleaning shaker balls and screens, trying to untangle them from the dishwasher rack, losing them in your cabinets, or replacing batteries. Helimix only requires the cup, lid, and your choice of supplement mix to operate. We know you put a lot of hard work into every gym session, game, and competition, so we want to eliminate anything in your path to domination. The Helimix uses shatter-proof, odor resistant, 100% BPA/BPS-free Copolyester plastic to give you a clean, American Made, durable and easy-to-wash shaker bottle.
