Atomic Four AMID helmet is a hugely popular model from the Atomic Four family, which brings a totally fresh approach to all-mountain helmet design. The unique combination of AMID technology and Holo Core offers up to 40% more impact protection than industry safety standards – this helmet will keep you perfectly protected anytime, and in any terrain. The helmet’s position on your head and how snug it fits can be fine-tuned with the 360º Fit System. Besides an urban-inspired, low-profile design, the Four AMID helmet also offers a removable liner and goggle clip, which let you ride with beanie and goggles underneath the shell if you want. Stand out, just don’t shout.

• AMID: A revolutionary dual-density foam system that provides up to 40% higher impact protection than industry safety standards.
• Holo Core: Crumple zones are designed to absorb the energy from the impact during a collision by controlled deformation. The impact absorption is 30% higher than CE requires.
  
• Aircon Venting: Aircon is Atomic's most advanced cooling system yet. The Holo Core offers wider and more air channels through each layer of the helmet which gives hot air room to escape and adjustable vents actively suck heat away from the head.
