What they say: Combines an airy, open design with a revolution in rotational energy management to advance head protection.
What we say: Giro helped to pioneer the development of MIPS (see introduction) so it’s not surprising to see this technology used here. Rather than merely being added to an existing helmet, however, the MIPS Spherical tech the Aether contains is very much integral to this helmet’s design.
Poking around the underside of it, you discover that there are two separate but connected layers of EPS one of which clings to your skull, while the outer layer almost floats independently on top of it, allowing up to 20 mm of movement left and right and about half that front and back.
It’s genuinely ingenious, not least because it means that unlike other MIPS systems, there’s no obstruction of the vents. In fact, the 11 vents proved very good at keeping our tester’s head cool in the hot weather, while internal sweat pads proved pretty effective at dealing with perspiration. It’s also a comfortable lid to wear.
Weighing 262 g, its Air-fit adjustment system has three functions that allow you to tinker with the tightness, height and positioning of its internal cradle. One little touch we especially appreciated was the inclusion of a pair of rubber grippers on the lower two vents, meaning there’s no chance of your sunnies slipping out should you choose to stow them up there. Available in a number of different finishes including yellow/ white, blue, black, black/pearl and red.
Conclusion: A superb helmet that employs the very latest MIPS tech, while scoring highly, too, for comfort and cooling.
