KASK Valegro or Protone Icon?

The Valegro exists because Team Sky asked KASK for a light, maximally cooled helmet to sit alongside the more aerodynamic Protone. It has 37 vents and KASK claims 180 g in a size small. The Protone Icon gives up some airflow for a smoother, slightly aero shell and is the better all-rounder. Pick the Valegro for climbing and hot weather, the Protone Icon for everything.

Do KASK helmets have MIPS?

No. Instead of the MIPS liner, KASK tests every helmet to its own WG11 rotational impact protocol, developed with the European standards working group that measures shock absorption from oblique as well as direct impacts. KASK helmets are also certified to EN 1078, CPSC 1203 and AS/NZS 2063.

How do I choose the right helmet size?

Measure your head with a tape about one centimetre above the eyebrows, at the widest point, and match that to the model's size range. On the KASK Mojito 3 for example small covers 50-56 cm, medium 52-58 cm and large 59-62 cm. If you fall between two sizes, head shape decides it, so come and try both in the shop.

WG11

KASK's own rotational-impact test protocol, developed with the European standards working group WG11. Every KASK helmet is tested for oblique as well as direct impacts, on top of EN 1078, CPSC 1203 and AS/NZS 2063 certification. KASK uses it instead of a MIPS liner.

Octo Fit

KASK's retention system: a rubberised dial you can adjust on the move, and a rear cradle with gel pads that pivots to follow the shape of your head. The Protone Icon and Elemento use the updated Octo Fit Plus.

Faux leather chinstrap

KASK's signature chinstrap in hypoallergenic faux leather. It is easy to clean, sits comfortably against the skin and helps avoid the irritation that fabric straps can cause.
