Amazing Ventilation, Not-So-Amazing Fit

I have worn a Kask Protone for a couple years. The Protone is an extremely high quality, extremely comfortable helmet so, when it was time to buy a helmet for hot weather, I bought the Valegro. First, the good news . . . this helmet provides amazing ventilation. The cooling effect for the forehead and crown of the head is far greater than for any other helmet I have ever worn. It was extremely noticeable from the very first moments of the very first ride. And, the helmet is of the same obvious premium quality as the Protone. Top quality stuff. Now, the bad news. Because of the ventilation, helmet pressure is concentrated on two points on the front of the head. On top of that, the Velegro seems to fit somewhat smaller than the Protone. Unlike the Protone that spreads the pressure across the entire forehead, the Valegro focuses all the pressure on those two spots. As a result, if you snug the Valegro normally, as you would the Protone, the Valegro will cause headaches within a few miles. Since I can't return the helmet after I've worn it, my solution is to wear the helmet looser than I would other helmets. Is this a safety problem? I don't know. Possibly. Because of this problem, I don't wear the helmet nearly as much as I originally intended. The Valegro is a fine helmet, but the pressure points are a natural result of the amazing ventilation design. If you can live with wearing the helmet a little loose, it's literally a very cool helmet! If you can't . . . don't buy it.

The Helmet I Forgot was on my Head!
by R.Bow

The light weight and superb ventilation of the Valegro is most welcome in hot weather. It's a wonderful feeling to forget it's on my head! The multiple adjustments give my hard-to-fit head and good fit.

For the 5th Star, I would like a MIPS version to maximize safety.

Love this helmet!

I was looking for a new helmet and decided on this one after extensive research. Great combination of light weight, airy ventilation, solid fit system, and good looks. Also really like the synthetic leather chin strap which is more comfortable and easy to clean. I realize people have different fit preferences but so far, have not noticed any pressure points. No issues or complaints that I can think of. Ordered a medium and fits great (head circumference is 22.5in or 57.15cm). Thanks!

I used to wear a Giro Synthe helmet but got tired of the design and it sat a tad too high for my liking. This helmet has very similar features to the Giro and more ventilation for those hot days. A solid 5 stars for this helmet!
