Aero road helmets have historically demanded compromise—accept the drag penalty of vents or cook your head inside a smooth shell. KASK's Nirvana rejects that trade-off entirely. Developed through computational fluid dynamics simulations and refined with direct input from the Ineos Grenadiers professional team, the Nirvana delivers a 35% reduction in aerodynamic drag while simultaneously improving ventilation by 19% compared to previous aero benchmarks. The teardrop profile and integrated ear covers channel airflow efficiently around the rider's head rather than creating the turbulent pockets that add drag and trap heat inside conventional aero lids.

The ear covers distinguish the Nirvana from conventional aero road helmets and represent a deliberate borrowing from time trial design. Rather than leaving ears exposed to disrupt airflow, the sculpted side panels extend down to cover the upper ear, smoothing the transition between helmet and shoulders while reducing frontal area. Internal channeling runs from the front vents through the helmet's core, drawing air directly across the scalp before exhausting through rear ports. This active cooling system maintains thermal regulation at speed, addressing the overheating problems that have historically plagued enclosed helmet designs on long climbs and warm days.

KASK's Multipod technology handles impact protection through 3D-printed internal padding that functions isotropically—absorbing energy consistently regardless of impact direction. This replaces traditional foam with a lattice structure that manages both linear and rotational forces while creating space for airflow between the padding and scalp. The design passed KASK's WG11 rotational impact protocol, an internal testing standard that exceeds international certification requirements. Merino wool padding at the front and sides handles moisture absorption and comfort, providing a natural fiber interface that resists odor buildup during repeated hard efforts throughout the season....
