Collection: LAS Helmets | Handmade Italian Road & Aero Cycling Helmets

To ensure a secure, comfortable fit, measure your head circumference horizontally approximately 1 inch (2.5 cm) above your eyebrows and directly above the ears:

• Virtus Carbon, Virtus & Cobalto: Size S/M fits 54 to 59 cm (21.3″ to 23.2″); Size L/XL fits 59 to 61 cm (23.2″ to 24.0″). Fine-tuned with the Nano 3D micro-dial system.
• Enigma: Size S/M fits 55 to 58 cm (21.7″ to 22.8″); Size L/XL fits 59 to 61 cm (23.2″ to 24.0″). Fine-tuned with an ergonomic tension dial.
• What if I'm borderline or between sizes? We recommend choosing the larger size. If you frequently wear thermal winter cycling beanies or sweat caps underneath, sizing up provides comfortable interior volume while the rear retention dial locks in a secure fit.

Each LAS helmet model is engineered for specific riding conditions and performance priorities:

• LAS Virtus Carbon ($262.00): Flagship aero-road helmet featuring an integrated carbon fiber structural reinforcement frame. Delivers unmatched torsional rigidity, reduced frontal drag, and low weight (255g S/M).
• LAS Virtus ($200.00): Pure road racing and climbing helmet equipped with 39 high-flow air channels for maximum heat dissipation, plus a premium Fidlock magnetic snap buckle for effortless one-handed fastening.
• LAS Cobalto ($149.00): Best-selling all-around performance helmet with 20 aerodynamic vents and the Nano 3D fit dial. Includes the iconic Celeste Bianchi colorway to match Italian road frames.
