Kask Valegro Road Helmet Black Information

Season : Helmets - Sale

Brand : Kask

Code : CHE00052-2

As worn by Team Sky on the hottest mountain days at the Tour de France, Kask's Valegro is by far their lightest and most ventilated helmet to date.

The mission set to Kask was to create an incredibly lightweight and ventilated helmet to take on the hot mountains in the 104th Tour de France, and with a whopping 36 vents, they managed it. Thanks to Kask's new moulding technology, the Valegro weighs in at just 180g, which is 70g lighter than the Protone, ensuring that it will give you that extra advantage when every second counts on hard road rides.

The profile of the Valegro's polycarbonate shell is the result of lessons learned from the Bambino Pro and Infinity helmets as well as relentless testing and refining in the wind-tunnel to guarantee the best results in terms of thermo-cooling performance. As well as the Valegro's 36 ventilation holes, it also features state-of-the-art 5mm thick fast-wicking material on the helmet's pads, ensuring that moisture is taken away from the rider's head, thus making you more comfortable and able to concentrate entirely on your performance.

The padding is also anti-static, bacteriostatic and heat regulating thanks to Resistex Carbon in order to consolidate your comfort, and the head-to-pad contact of the helmet is an incredible 70% less than other helmet designs. Alongside this cutting edge technology in terms of its light weight, aerodynamics and comfort, the Valegro is topped off with an eco-leather strap and chin pad as well as front and rear sunglasses garages, that contribute to a helmet that is comfortable to wear all day.

  • Small - 50-56cm
  • Medium - 52-58cm
  • Large - 59-62cm
Technical Information
  • HyVent - Structure and design of the shell implement the air flow and break up the exchangeable heat.
  • High Breathability - Because the inner padding fiber speeds up the evaporation process of perspiration, slows down the formation of humidity on the skin and keeps the temperature constant.
  • Anti-Bacterial - Because the inner padding fiber respects the skin and protects it from bacteria and pollutant dusts; eliminating the risk of annoying allergies.
  • Anti-Static - Because of its conductivity, the inner padding fibre absorbs and disperses electric charges accumulated from the environment or during physical exercise.
  • 3D Dry Padding - The tridimensional 3D Dry padding utilises a multi-layer open cell construction process: high technology for the best comfort and performance. The rubberised Micro Dial adjuster provides improved finger grip, its floating cradles contact points combine internal gel pads for optimum comfort. These supports are designed to oscillate freely through 180° allowing a perfect fit on any shaped head. The Skeletal Brackets of the cradle have been designed and refined to provide the best fit and support whilst being as light as possible.
  • Octo Fit - The anallergic and washable chinstrap is extremely comfortable and helps to avoid irritation of the skin.
  • MIT - The MIT Technology - applied to all Kask cycling helmets - guarantees higher safety and complete protection thanks to the polycarbonate layer that covers the shell on the top, on the base ring and on the back.
  • In-Moulding - The innovative 'in moulding' technology joins the inner polystyrene cap to the outer polycarbonate one, ensuring a better shock absorption.
