The Stilo ST5 FN Carbon FIA8860-2018 Helmet boasts an autoclaved medium tensile carbon construction, resulting in a remarkably lightweight and highly protective design. Ideal for open-cockpit racing, this helmet exceeds the latest FIA 8860-2018 safety standards while offering unparalleled performance in terms of weight and aerodynamics. To reduce weight, electronic and side ports have been omitted, but this helmet is compatible with side and frontal drinking systems. Additionally, it features eight ventilation holes that can be integrated with Stilo Helmets Top Air systems. The earmuffs are designed to provide superior noise isolation and are certified for track use, with the added convenience of adjustable pressure and removable options.

Stilo sizes are head circumference in centimetres — a size 57 helmet is built for a 57 cm head. Measure around the widest part of your head, about 1 cm above the eyebrows and above the ears.
Stilo run a little smaller than most other brands. If you fall between sizes, or measure a number Stilo does not make (53 and 62 are not produced), take the next size up and tighten the fit with cheek pads (20–35 mm) or crown and earmuff fitment pads.
Not every model offers every size: the ST5 range skips 56 and 58, the ST6 range skips 60, and the Venti Sport helmets are offered in 54, 55, 57, 59 and 61 only. Check the size selector on the product.
Shell sizes: ST5 and ST6 use a small shell for 54–59 and a large shell for 60–64.
Where dealers quote letter equivalents: 55 = S, 57 = M, 58 = M/L, 59 = L, 60 = L/XL, 61 = XL, 63 = XXL, 64 = XXXL. Stilo itself sizes only by number.
Sizing is from the manufacturer and varies between brands. Measure yourself and compare against the table rather than ordering your usual street size.
