Haylou Solar respects the trend through minimalist design. Streamline housing gives a unique sport style that makes you keep moving. Like its name, Haylou Solar features a metal body in an arc shining on your wrist. With more colors and details, the 1.28-inch screen delivers pictures that feel real and vivid. No matter whether in intense light or at night, all details are shown clearly. Thanks to nano light wave technology, the soft silicone watch strap allows your wrist to breathe even if it gets sweaty. With the multi-hole design, the band is lightweight for long-term wear and adjustable for different wrists. Up to 12 sport modes are available which allow you to use Haylou Solar when and where you want - fearlessly. No worries about power, sweat, or rain, just embrace the idea of sport life. Quality Li-ion battery offers ultra-long battery life. One top-up means 30 days of standby or 15 full days of heart monitoring. Low battery warning gets your focus on the surprises filling in the outside world. Thanks to IP68 waterproof, Haylou Solar is resistant to sweat or rain. Just wear it to do whatever you do in your daily life.
