The Eclipse Spherical is also one of the most stylish-looking helmets around and one of the most advanced in terms of safety. The Giro features, like most of the market-leading helmets, the MIPS safety system – the protection system designed to address rotational motion for an added measure of protection in certain impacts. The MIPS system is paired with a dual-density EPS foam liner, designed to address high and low-speed impacts for more comprehensive energy management.

Elsewhere, the Eclipse Spherical has plenty of vents with internal channelling that allow air to flow through the helmet to enhance cooling. In-mould construction keeps it light, and it weighs in at just 270g. The far more costly Specialized S-Works Evade III weighs in at 295g and costs $300.

With the current Amazon discount on a helmet that our experts rate as the best helmet for road cycling, it's a very attractive option worth grabbing fast.
