Expensive, even on discount, so I would say it's a reasonable good helmet.
Fit on a round head is very good. It's probably very aero by its shape, and I think it flows air reasonably well.
Personally, my ears didn't interfere with the half covering from the helmet.
Size M doesn't feel heavy at all.
One common con for KASK helmet is that sweat will drop down from the front padding when it's fully soaked up.
Overall very satisfied with it. I will see how it feels under the sun when summer comes.
Product Review: Mask Nirvana Helmet
As a long-time fan of the Proton helmet, I had high expectations when I decided to try the Nirvana for my aero needs'and it did not disappoint. From the moment I put it on, I was impressed by the level of comfort. The padding feels premium and molds to your head perfectly, making it ideal for long rides.
One of my favorite features is the ratcheting system. It's intuitive, precise, and allows for easy adjustments on the go. Whether I'm on a steep climb or pushing hard on a flat stretch, the helmet stays securely in place without any discomfort.
When it comes to performance, the Nirvana truly shines. It feels fast'really fast. The aerodynamic design is noticeable, especially in high-speed scenarios, where every watt saved counts. I've already shaved some time off my personal bests, and I credit a lot of that to this helmet.
Overall, the Kask Nirvana helmet is a worthy upgrade for anyone looking for speed, comfort, and functionality. If you love the Proton, you'll be just as thrilled with the Nirvana. Highly recommended!
