We grabbed our first glimpse of the Kask Valegro Helmet on
the heads of Team Sky riders at the 2017 Tour as they donned them on the
hottest mountain stages where aerodynamics takes a back seat to light weight
and ventilation. Since that time, we've been patiently waiting for Kask to
bring the helmet to the market for us mere mortals. The team that's known for
its obsession with marginal gains once again makes—ahem—headway in helping
design a product that in the end, we all benefit from.
Kask engineers carefully shaped the profile of the Valegro's
polycarbonate shell and verified the results in the wind tunnel, creating
exceptional cooling performance and heat exchange, the perfect recipe for a
helmet to keep your head cool on climbs in July. The Valegro offers its
impressive cooling through 37 vents and the new breathable and quick-dry pads.
This 5mm thick 3D DRY padding is anti-static and antibacterial and has a
multi-layer open cell construction process so it wicks away sweat while
remaining extremely comfortable. And because your perspiration evaporates
quickly, less humidity is formed so the temperature remains more constant.
Kask and Team Sky both realize that a well-ventilated helmet
doesn't amount to much if it isn't safe so it uses in-molding technology to
join the inner polystyrene cap to the outer polycarbonate which ensures better
shock absorption. This helmet, like all Kask helmets, features MIT Technology,
that Kask touts as being safer and offering more protection due to the fact
that the polycarbonate layer covers the top of the helmet as well as the base
ring. Keeping the helmet in place during the ride and an unfortunate event of a
crash is its much-lauded Octo Fit system. A rubberized dial adjuster provides
easy two-finger adjustment of the floating cradle's contact points for comfort
and they oscillate freely through a 180-degree range allowing for a perfect fit
on a variety of head shapes. Another returning favorite is the eco-leather
chinstrap that’s way more comfortable than a salt-encrusted nylon webbing strap
sanding away at your jaw and chin.
The Valegro manages all this amazing ventilation and safety
at the impressively low weight of just 180g in a size small. It's no wonder why
the pros on Team Sky choose this helmet on some of the hardest stages and it’s
the one we'll be rocking on our own heroic rides.

How to Measure:
Measure around your head where your hat would fit comfortably.
ride a lot but had it less than a year. inner pads gone. velcro digging in head. retention system breaks continually. but I'm able to take it apart and fix it. takes 10 minutes. very light. breaths. like the tilt feature of the band. impression: better than average.
The Kask Valegro is a super light helmet. The Octo Fit retention system keeps the helmet nice and secure on your head. I use this helmet with some Oakley Jawbreakers and have issues keeping the Jawbreakers arms held in the helmet vents. Side profile of the helmet is pretty good, it doesn't stick out too much. Fits pretty well for a large head, my hat size is 7 5/8.
Out of the box, this helmet is light. Substantially lighter than my previous Bell Zephyr. I've already used it on a couple 85 degree + rides, and air flow is excellent. The helmet has a nice aero profile, with a trim back end. But the real aero benefit is not obvious until you actually ride with the helmet. Their is very little material (not even padding) at the front center (ie. between your eyebrows, center of forehead). This allows a better flat back position, as the brim of the helmet doesn't interfere with vision. The front corners of the helmet are built up for protection, so you're covered in the event of a crash. The lack of padding above the eyebrow also serves another feature: no sweat dripping into your eyes. The fit adjustment works fine. As for fit, the helmet is typical kask: rounder fit. I have a more oval shaped head, 59cm. I went with a large, and there is a bit of room on the sides. However, the fit is secure. The valegro also has a smaller profile than the kask protone. I would highly recommend the Valegro.
