Poor hydration affects how you look, feel, recover and perform. Sixty aims to inform users of current hydration levels, advise them of ideal fluid intake and educate them about associated symptoms and risks. Using a highly accurate photonics technology, the device can detect hydration and heart rate, correlating the data to pre-empt, intervene and ultimately prevent improper hydration. Functional both as a wearable and standalone device, the Sixty system is universally appealing and accommodates a wide variety of users and usage scenarios.
