Described as aero perfection, Kask says its new helmet is designed to guarantee minimal drag while delivering optimal comfort. It’s firmly targeted at road and track cyclists and triathletes who seek aerodynamic advantages over their competitors and fellow riders. Kask says that the development of this aero helmet utilised complex computational fluid dynamics simulations, which measured aerodynamic performance, ventilation, and thermoregulation. Now, that’s a huge mouthful of words, but in short, the company has developed an impressive aero helmet.
Kask claims that the development process has resulted in a 35 per cent lower drag and a 19 per cent increase in ventilation compared to the Utopia Y, the existing Kask aero model. And while it’s not possible to verify these claims, the helmet really looks the goods on aerodynamics.
The first thing I noticed about the new Nirvana is the lower sides, or ‘ear covers’ as Kask calls them, that cover the top of your ears. I assume this is to make it more aero because ears tend to stick out and produce drag, but it has the added benefit of being warmer in cooler weather. My usual helmet is a more conventional design that doesn’t cover my ears in cold weather, so I wear a headband to keep my ears warm.
The next thing I found was the waffle-type pads on the inside of the helmet. Kask says this multi-pod technology, 3D-printed internal padding is designed to withstand linear and rotational impacts better. It functions isotropically, meaning it behaves the same […]
