Kask's Protone helmet is part of a new generation of "semi-aero"
helmets, which combine the benefits of an aero shape with a decent
amount of ventilation.
Weighing just 215g in a size Medium, the Protone is remarkably
lightweight for an aero helmet. Together with thick padding and
large vents this makes for a comfortable helmet that retains good
Kask have even ensured that you can hold your glasses in the
vents of the helmet without any major compromises to aerodynamic
efficiency - a clever touch that shows their level of attention to
detail and real-world practicality. These helmets are proven in the
peloton, and that Pro feedback is invaluable.
An internal plastic sub-frame provides extra crash protection,
helping keep the helmet together in the event of an impact, and
wide lightweight straps ensure a secure fit.
The Protone uses a 3D Dry padding with a multi-layer open cell
construction process to give a more comfortable ride.
It has removable and washable inner padding, made from CoolMax®
fabrics and its inner padding fabric has been treated using the
Sanitized® antimicrobial process.
KASK has also continued to use its Multi In-Moulding Technology
to create a polycarbonate cover for the top, base ring and the back
of the helmet's shell. This is joined to the inner polystyrene cap
via KASK's In-Moulding Technology to improve the shell's shock
absorption. Its strengthened frame further reduces the risk of a
shock breaking the shell.
