A revolutionary bottle that keeps drinks refreshingly cold with refined function and style. The  radian stainless steel shaker features rock-solid insulation, a modern, center-mounted spout, a clever carry loop, and our most secure seal to date. Say 'goodbye' to lumpy protein shakes and 'hello' to smooth, great-tasting drinks. Our patented mixing system uses the blender ball® wire whisk-found only in brand shaker cups-to mix even the thickest ingredients as you shake. You'll wonder how you ever did without it. Ensures an icy-cold drink for up to 24 hours, with zero condensation on the bottle. The radian shaker's new flexible carry loop detaches at the base, making it easy to attach keys or clips to a gym bag. The stylish center-mounted spout closes with a quick quarter twist, delivering a stronger-than-ever seal and increased peace of mind. With its tapered base, the radian shaker fits easily in most car or gym equipment cup holders. Whether you're carrying protein, a smoothie, or just plain water, you can rest assured that you have a tight seal. Like all  brand shaker cups, the radian shaker is made from high quality, BPA- and phthalate-free materials.
