The premier Carbon Downhill MTB Helmet from 100% has landed.

The Aircraft is precision engineered with a Carbon/Kevlar Composite shell providing an exceptionally strong, yet ultra-lightweight design.

25 enhanced venting channels create the Active Cooling System; specifically designed to manage air flow and ventilate the entire helmet.

The AIRCRAFT CARBON also features the MIPS Brain Protection System; a helmet-integrated, low-friction layer designed to reduce rotational motion transferred to the brain from angled impacts to the head.

Ultra-light Design: Featuring aerospace Carbon/Kevlar Composite shell

By melding Kevlar and carbon fiber, the Aircraft achieves the best of both worlds: Kevlar’s unyielding resistance to damage and abrasion (think bulletproof vests) and carbon’s superior strength, making for the best of both—the lightest weight, strongest combination highly resistant to damage from impacts.

Active Cooling System: Maximizes airflow with a staggering 25 ventilation ports.

Spend more time concentrating on riding the trail and less time overheating your brain with the Aircraft’s integrated Active Cooling System with its 25 strategically placed air vents.

Integrated MIPS Brain Protection System to counter angled impacts.
