Garmin Vivosmart 4

Accent your style while enhancing your fitness with our Vivosmart 4 activity tracker. This slim  swim-friendly wearable comes loaded with fitness and wellness features to help you make the most of a healthier, more active lifestyle. A wrist-based Pulse Ox sensor lets you estimate blood oxygen saturation while you're sleeping – or you can spot-check your oxygen levels anytime during the day. The device also monitors heart rate at the wrist and includes helpful tools such as all-day stress tracking, a relaxation breathing timer and VO2 max readings. Plus, Body Battery energy monitoring helps you know when you're primed to be active or when you may need to rest. Safe for the pool or shower, Vivosmart 4 keeps you going strong with up to 7 days of battery life – while smart notifications with vibration alerts help you stay connected on the go (when connected to a compatible smartphone).
