Given a glowing 4.5 star review in our helmets buyer’s guide last month, the Eclipse Spherical (£239.99) is billed by Giro as both the fastest road helmet and the coolest aero road lid that they’ve ever created.
It brings the American helmet titan’s best technologies together in a light, compact form that’s ideal for road and gravel racing. The sleek outer shell streamlines airflow to reduce drag across multiple wind angles, while the 14 Wind Tunnel vents pull air through the helmet to provide cooling power that rivals the Californian’s most aggressively vented road helmets.
Within the helmet, the ball-and-socket design of Spherical Technology is powered by the MIPS brain-protection system, which allows the helmet’s outer EPS foam liner to rotate around the inner foam liner during a crash to help redirect impact forces away from the brain.
‘Progressive Layering’ of both the inner and outer liners helps to offer more comprehensive protection, too. The patented Roc Loc 5 Air system enhances the stability and fit, while the plush antimicrobial Ionic+ padding helps absorb sweat and moisture while providing durable antimicrobial performance at the same time.
