📏 How to Measure Your Head for Official LAS Helmet Sizing
To ensure a secure, comfortable fit, measure your head circumference accurately before ordering. Wrap a soft, flexible measuring tape horizontally around the widest part of your head—approximately 1 inch (2.5 cm) above your eyebrows and directly above the ears. Keep the tape level and snug but not tight.

💡 Between Sizes or Borderline? If your head measurement falls on the boundary or between sizes, we recommend choosing the larger size. If you frequently wear thermal winter cycling beanies or sweat caps, sizing up ensures ample interior volume while the rear Nano 3D micro-dial provides secure, millimeter-precise tightening.
