Four Amid Pro Helmet

This year, Atomic decided to take a new approach to their all mountain helmet design. The Four Amid Pro Helmet is the pinnacle of this, with sleek, street-inspired style, a comfortable fit, and protection you can ride in with confidence. Built with AMID, which stands for Atomic Multi-directional Impact Deflector, the helmet's defense systems are designed to absorb the force of angled impacts, while the Holo Core design incorporates a crumple zone that maximizes shock absorption.

  • Ride confidently in this low-profile, urban-inspired helmet
  • Hybrid in-mold construction is lightweight and stable
  • Multiple layers of protection help absorb forces when you fall
  • Advanced ventilation system actively moves heat away
  • 360° fit system adjusts with the gloved turn of a knob
  • Merino 3M X-Static lining manages moisture and odors
  • Item #ATOK189

First off, this helmet is sweet! It fits like you want it to, is lightweight and warm, and even has a subtle design on the back of the black version courtesy of Chris Benchetler. I used it for about 15 days before my accident. I was skiing at Solitude off of the Summit chair and clipped my head on a tree, tumbling down about 50 yards thereafter. I would be in a very different situation right now if I wasn't wearing this helmet. I am ordering another one right now.


First of all: it’s great that you were safe and well protected. Second of all: how fast were you going!? Damn man you must’ve been cooking if you dented a helmet!
