The GT-Air II is the helmet that defined the integrated sport-touring formula: AIM shell, QSV-2 internal sun shield, a CNS-1 face shield with Pinlock EVO lens included, and a shell designed from the start around the SENA SRL2 communicator.

How to measure
Pass a soft tape measure horizontally around your head about one inch (2.5 cm) above the eyebrows — the largest measurement around the forehead. Move the tape slightly up and down to find the largest reading. If you fall between two sizes, try the smaller size first.

One official SHOEI US chart for all adult models; fit can feel different between models at the same size, and size runs vary per model (3XL only on select models). SHOEI publishes no US youth street chart. 2XL/3XL appear as XXL/XXXL on SHOEI's own chart — normalized here to match our size filter vocabulary.
