Key characteristics
Highlights
- ✓ Spherical MIPS (ball-and-socket) rotational protection
- ✓ Among the best impact scores in independent testing
- ✓ Deep internal channels for outstanding airflow
- ✓ Light for a fully-featured road helmet
Our take
The Aries is the helmet that tops the tests: Giro's Spherical MIPS scores near the top for rotational protection, ventilation is genuinely class-leading, and it's light and comfortable all day. It's expensive, but if you want the best-protected, best-ventilated road helmet in one, this is it.
