Atomic Snow Helmet The Four AMID Pro from Atomic is a perfect helmet for skiers looking for a simple look, protection and endless features. Atomic's Holo Core Technology exceeds safety standards by 30%, reduces weight and increases air flow through the helmet to keep you comfortable and protected on the mountain. The Live Fit 360 Fit System uses a dial for fine tuning and padding that conforms to your head shape for a truly dialed in and comfortable fit. AMID (Atomic Multi-Directional Impact Deflector) Technology has a dual density foam that is connected to the helmet core that can rotate upon impact to absorb energy and reduce the amount of force put on your brain, should you take an impact. Atomic's Hybrid In-Mold Construction is remarkably lightweight and you will barely notice that you have a helmet on your head. Aircon Venting allows you to not overheat and stay dry by having more wider air channels throughout the helmet to allow hot air to escape the helmet and help you keep a cool head on the mountain. A RECCO Reflective Device has been added, just in case of an emergency in the backcountry. If you want a ripping helmet that keeps you cool, comfortable and looking good, the Atomic Four AMID Pro is the perfect choice for you.
