Chin strap held on the helmet by 4 rivets. Adjustable nylon straps with double adjustment (adjustment triangle for front/back lengths balanced or uneven), a fast self-locking buckle (dual-lock) and an anatomically designed pad. Fitted to the back band. The nape protector is anatomically designed, and covered by leather. It can be moulded for a better adjustement. Fixed on the harness of the chin strap (not the helmet) to allow the ideal positioning of the helmet and ventilation of the back of the neck.

Outer shell in heat-formed injected composite and coated, with a new paint "soft". GPA signature on the front.

Front air inlet strip in a light alloy of titanium and aluminium, with 4 vents, painted with a special "soft" paint". This patented system with a double air flow provides internal ventilation as well as keeping down the temperature.

Head liner in "aerated" foam covered by high-tech antibacterial fabric. Made up of 4 independent parts (front, central, right and left). This washable liner is removable and can be replaced or adapted.

Inner shell lining in high-tech high-density polystyrene. Ergonomic shape ensuring real comfort and the excellent "retention" of the helmet.Cut-outs at the air inlets. The incoming air is channelled through the grooved structure of the inner shell and evacuated through 2 vents at the back. This ventilation system (tested in a wind machine) adds to the real comfort of the rider and eliminates the unpleasant effects of the sweating and heating of the scalp.
