White LEDs — forward visibility
A bright white arc across the brow throws light onto the trail and signals the rider's heading to anyone approaching from the front.
A helmet that keeps breathing after the fall.
AERIS is a snow-sports helmet with an integrated airbag array and a 1.5 L oxygen reserve — designed to keep alpine riders alive through the first critical minutes after a buried fall, long enough for patrol to reach them.
Product renders on-site — the helmet as it's meant to be worn, before the rest of the case study walks you through how it got there.

Three lifelines engineered into a single shell — impact absorption, a breathing-air reserve, and an always-on illumination system. Scroll through the walkthrough to see each of them.
Every serious snow brand has a flagship impact helmet. Every serious brand charges $250–$500 for it. None of them do anything after the first impact.
The visual language borrows from automotive safety — carbon-black shell, high-gloss dome, single alpine-red accent where the system wakes up. Calm on the slope; obvious on the snow.









Before any CAD, the two bets — airbag array and oxygen reserve — had to fit on a helmet shape a rider would actually wear. This sheet was the first place the silhouette, the venting, and the chin-bar oxygen module sat together on paper.
Five candidates ran through impact, weight, cost, and moldability. The PC-hybrid sat in the middle of every axis — production-ready, strong enough, and moldable enough to host the airbag layout.
Every revision came from a crit session, ski-patrol feedback, or a bench test. The final shape was the fifth answer to the same question.
White LEDs up front light the line of travel; red LEDs along the back make the rider legible from behind — a single continuous ring driven by an Arduino controller.

Red pixels along the rear of the rim keep the rider visible to anyone following — the same ring doubles as a distress beacon on impact.

An exploded breakdown of every layer keeping the skier alive.
An integrated 8-airbag array offers supplementary protection in high-impact moments.
A high-gloss composite shell resisting abrasion and point impacts on the slope.
Integrated control module — battery, chips, and the central controller for the airbag system.
Shaped memory-foam liner cushions the head and keeps the shell aligned while worn.
Load-bearing inner frame transferring impact energy outward from the skull.
A pressurised gasket isolating the internal systems from snow and moisture.
A 1.5 L oxygen reserve — 6 additional minutes of breathing, raising survival probability by 44%.
