It's all about making health tracking a breeze, without the bulk. Speaking of which, the R5S model in Pink, Size 9, is so comfy you'll forget it's there—until it reminds you to move, that is. With a snug inner diameter of 19mm (0.75in), it's the perfect blend of form and function for your daily grind.
