Kask Infinity Aero Road Cycling Helmet

The Kask Infinity Aero Road helmet is the first to feature adjustable vents; this clever approach to helmet design gives you a versatile aero helmet which adjusts to provide maximum aero performance with the vents closed and optimum ventilation with the vents open – perfect for warmer days and long climbs.  

Developed in partnership with the Team Sky professional cycling team, Kask’s design brief was to create an aero helmet that equaled their fully closed helmets in terms of aerodynamic performance but also offered the right level of ventilation for long hot days racing in the peloton. With the final design informed by feedback from Pro cyclists Kask produced an easy to open venting system – simply slide open up for temperature management on climbs and close fully to meet the aerodynamic demands of high-speed racing. 



The Kask Infinity Aero Road helmet features 3D DRY padding inside the helmet for enhanced comfort and performance, an eco-leather chinstrap which is anallergic & washable and helps to avoid irritation of the skin, a rubberised Micro Dial adjuster on the back of the helmet and a floating cradle with internal gel pads for optimum comfort. All Coolmax inner padding has been treated with an antibacterial and antimicrobial process to help keep the helmet fresh and odour free. High visibility stickers on the rear of the Infinity aero helmet provide extra rider-safety in poor conditions.

Mr Davies Excellent product offering aero features. It's all about marginal gains and this helps
Charlie H Fantastic helmet very comfortable with plenty of adjustments. Lid closed ideal for cooler weather
Joel I love this helmet. Snug fit. Top quality material. Really really reduces wind drag. I ordered it before they put the discount on all Kask helmets, anyhow it is still worth the money.
Mr Harrison Very pleased with these helmets. One for myself and one for my wife both a very good fit and comfortable. So light it hardly seems you are wearing it. Excellent service from Merlin.
M. Raven Feels very comfortable and well ventilated, even with the vents closed. I've owned both the Giro Air Attack and Specialized Evade. The Kask Infinity is definitely much better ventilated than both, and feels nearly as good as the Kask Protone. The only slight negative is perhaps the weight.
