The Giro Helios Spherical is the US brand's second road helmet to use Spherical MIPS protection, the first being the £269.99 Aether which we awarded a perfect score and which made our Editor’s Choice line-up in 2020.

The Helios has a lower price and an expanded remit: whereas the Aether was designed and styled purely for the road, the Helios is for “road cyclists, gravel enthusiasts and adventure riders.”
