If you're the competitive cyclist sick of sweaty chest straps, which can be a distraction that affects your performance, LifeBEAM's SMART cycling helmet might just be what you need. SMART uses similar technology to the one used in jet fighter pilot helmets that monitor the pilot's vitals to improve performance and potentially save his life. No uncomfortable chest straps and no distraction. It measures heart-rate, blood flow, oxygen saturation, and more using LifeBEAM's unique sensing technology. The data can be displayed on a smart phone, certain sports watches, and cycling computers so you can make the best out of the ride.
