Lazer has taken design elements from its range-topping Z1 and combined them with a front and sides that have a hint of the Genesis, and a unique rear end, to create the Blade.

- A helmet is born: Kask's Protone from start to finish
An in-moulded polycarbonate shell protects the outer surface and edges of the scruffily finished EPS core, but the underside is mostly left to fend for itself.
Fit is adjusted by sliding the rear occipital cradle to the most appropriate of its five heights and tightening the plastic band that encircles the head’s diameter with the top-mounted Rollsys barrel adjuster.
Between the head and EPS shell is the MIPS’s perforated yellow plastic layer with four slim X-Static pads and conventional webbing straps fastening it in place.
Performance
My large helmet weighed 337g, no featherweight, but hardly anvil-like. Of the 22 vents, two large V-shaped ones low down at the front gulp in plenty of air and the remaining, mainly rectangular vents help maintain consistent cooling.
Six shallow internal channels keep air flowing well between the EPS and MIPS layers, and it remained noiseless in all head positions, whatever my speed.
Matching the vent pattern, there’s quite a lot of the MIPS layer in contact with your head, despite the pads, which can partly negate the venting effects on hot days.
And the front pad, while effective at mopping moisture, can sit low and press firmly against the brow.
