Should I choose the S-Works Evade 4 or the Prevail 3?

The Evade 4 is the aero helmet: a closed shell shaped for speed, for racing and fast group rides. The Prevail 3 is the ventilated one, built around maximum airflow for heat and long climbs. Specialized quotes roughly 290 g for the Evade 4 and 250-260 g for the Prevail 3, so the Prevail is also the lighter of the two.

What is Mips Air Node?

Air Node is a version of the Mips rotational-impact system built into the helmet's padding rather than added as a separate plastic liner. That keeps the vents clear and saves weight, which is why Specialized uses it on both the Evade 4 and the Prevail 3.

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.

AirCage

Woven aramid fibres placed inside the shell. Specialized uses them to spread impact force through the helmet, which lets the vents be cut larger than the foam alone would allow — the reason the Prevail 3 can be this open and still pass certification.

Mips Air Node

A version of the Mips rotational-impact system built into the helmet's padding rather than added as a separate plastic liner, so the vents stay clear and weight stays down. The Evade 4 uses the Air Node Pro variant; the Prevail 3 uses Air Node.

Description

The S-Works Prevail 3 is Specialized's ventilated road helmet, the one to reach for in heat and on long climbs. Removing the foam bridges through the centre created open air channels that Specialized says increase ventilation surface area by 24.5% over the S-Works Prevail II Vent. Claimed weight is 250 g in a small and 260 g in a medium, making it the lighter of the two S-Works road helmets.
