The Atomic Four Amid Pro CTD Helmet is a high-tech yet understated solution to your on-hill safety. Atomic's Holo Core Technology surpasses safety standards by 30% while remaining lightweight and well ventilated. But that's not all: the Four Amid Pro CTD incorporates Atomic's revolutionary Shocksense Smart-Helmet Technology. Using an in-built SOS function, the Shocksense App sends an SOS alert with GPS data to your emergency contacts when impact force exceeds a certain threshold, and its sensors will let you know if the helmet is still safe to use after a crash. If you want maximum peace of mind while you ride, the Atomic Four Amid Pro CTD Helmet is an easy choice.
Hybrid In-Mold Construction – Combines the best of both worlds in helmet construction. The upper is made from ABS hard-shell for extra stability and protection. The lower is in-mold to keep the weight down.
HOLO Core – This unique 'egg-carton' construction creates an extended crumple zone for maximized shock absorption. It also comes with ventilation holes so it's cooler and lighter. This means up to 30% higher impact protection than industry standards.
AMID – The Atomic Multi-Directional Impact Deflector is a revolutionary dual-density foam system that is fixed to helmet's core and free to move in all directions. Provides up to 40% higher impact protection than industry standards.
Active Aircon Venting – With wider and more air channels through each layer of the helmet, hot air has room to escape and adjustable vents actively suck heat away from the head.
360° Fit System – This progressive fit system enables yo to fine-tune the helmet not only to your head size but also your head shape. It's also height-adjustable for 100% personalized comfort.
Live Fit – Live Fit pads surround your head 360° and mold to your head shape for an instant individual fit. They also dampen low-level impacts before the shocks can reach your head.
Shocksense Smart-Helmet Technology – Shocksense uses a sensor inside your helmet to transmit impact data to the Atomic Shocksense App. It determines whether you need to replace the helmet and can send an SOS alert, as well as your GPS location, to emergency contacts. Meaning you’re free to push your limits with total confidence in your equipment.
