D3O® Provides Impact Protection in the New STX Aero™ Helmet

D3O®: Advanced Protection Where It Matters Most

The STX Aero™ Helmet has D3O® shock-absorbing material, strategically placed above the forehead to reduce the transfer of force on impact. This cutting-edge technology remains soft and flexible during regular play but instantly stiffens upon impact, helping to minimize the risk of head injuries.  The Aero is  the only lacrosse helmet integrating this protection system.

Light, Aerodynamic Design

With D3O® preserving added weight, the STX Aero™ Helmet is more than 30% lighter than the previous STX Rival helmet, making it the lightest adult lacrosse helmet currently in the market. Designed in collaboration with elite athletes, Aero delivers an aerodynamic, barely-there fit that enhances agility and comfort, helping players perform at their best.

Cooler, Clearer, More Comfortable Play

Beyond protection, Aero features the AEROFLO™ ventilation system, incorporating 11 strategically placed vents that promote multi-directional airflow, keeping players cool during high intensity play. Its odor-resistant liner repels moisture to maintain freshness. Additionally, players have praised the superior field visibility of the Aero, ensuring a clear line of sight for improved reaction time and situational awareness.

Custom Fit & Branding Space

The FIT-SENSE™ click strap allows for precise rear adjustments, while removable padding enables further customization for a secure, comfortable fit. Aero also features an expanded CNVS™ coverage zone, giving teams more space for decals and custom branding, a standout advantage over helmets with smaller customization areas.

Exclusive Innovation for Goalies

For goaltenders, Aero introduces a custom throat guard system that attaches without the need for drilling into the helmet’s jaw, enabling full coverage without compromising the structural integrity of the helmet. 

Certified Protection & Built in Baltimore

The STX Aero™ Helmet meets NOCSAE standards and is certified by the Safety Equipment Institute (SEI). Additionally, STX has received independent certification to build and assemble custom helmets at its Baltimore headquarters, reinforcing its commitment to high-quality American craftsmanship.

With D3O® protection combined with ultralight construction, superior ventilation, and custom branding potential, the STX Aero™ Helmet provides the ultimate protection and comfort for lacrosse players.
