    Details

    Streamlined for speed.

    Though you might not think about it, chances are your cycling helmet is causing extra drag when you're chasing your friends down lonely stretches of highway and sprinting all-out at regional race events. The Kask Infinity Helmet offers an aerodynamic solution to your high-drag helmet woes with its streamlined shape and switchable front vents for adjustable aerodynamics with the flick of a switch.

    This aerodynamic helmet is the same that's used by Team Sky, Drapac, and other professional outfits. And for good reason too. In fact, overall drag on a bike can be reduced by an astonishing 14% with an aero-optimized helmet. When every bit of energy matters in racing scenarios, the Infinity Helmet is your best bet for reducing drag and gaining a competitive edge.

    Not content with merely being a one-trick pony, the Infinity is a functional helmet with adjustable venting. The front vents quickly open with a switch located at the top of the helmet. This allows you to adjust the venting with one hand when you're cranking at a high cadence. Keep them fully open when you're climbing and riding under the sweltering summer sun and close them when you're sprinting, chasing, and descending.

    Keeping you protected from nasty spills, the helmet's polycarbonate outer layer is bonded directly to a polystyrene core for enhanced shock absorption. Softening secondary impacts, Kask's Frame technology consists of a lattice of Kevlar-like material that prevents the helmet from fragmenting upon impact. Plus, you'll find Kask's signature touches for extra comfort, such as its Eco-Leather straps and antimicrobial CoolMax padding that's removable and washable for easy care. Moreover, Kask's Micro Dial retention system keeps the helmet nice and secure with minimal fuss.

    Cool helmet with some issues

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: Large

    I saw this helmet on GCN and the guy said that it was really good for cold weather because you can l close the vent making it aerodynamic AND keep the wind out. So I bought the helmet. I always wear a size large in every helmet I've ever owned. When I tried it on, it would not go over my head. Darn! What the heck, right? I returned it. My LBS was surprised it would not fit because he said it was actually pretty roomy. He asked, "Did you open it up?" I asked, "What"? "Did you pull the adjuster knob down"? So, there's an adjustment knob assembly at the back of the helmet that you need to pull down and open up so that you can get it on your head. Duh-oh! When I pulled it down and opened to adjustment knob, it fit like a charm. The problem in that the first time I wore it, when I went over bumps, the air vent door rattled! It sounded like something in my front end was rattling - but it was the helmet door! The good news is, it's comfortable, fits well, looks pro, and gives you a ventilation option. The bad news: it rattles when you hit a bump.

    Great helmet BUT...

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Large

    First of all, the helmet does not run small. It is just shaped for people with round heads and not oval. I have a really big round melon :) and all Kask helmets seem to fit me very well. However, I am running in a major issue with the helmet that I am not sure what to do about. The rear adjustment strap does not stay in the position and constantly gets loose. My other Kasks do not have that problem. Since I used it several times now, I am not sure I can still return it to Competitive Cyclist and even if I do I am not sure if a new helmet would solve the issue. Thoughts?

    Really Small

    • Familiarity: I returned this product before using it
    • Fit: Runs small
    • Size Bought: Medium

    I measured my head three times, ordered a medium and it was WAY too small. Rechecked the size on the box and the tag inside the helmet, both gave the same size in cm for head diameter. Maybe take them up on the $7 try them all deal. I'll post again when I get one that fits.

    In fairness to Kask, I want to add to my reviews and comments about size. My head shape is what they call a long oval for motorcycle helmets. I think the problem with the Kask helmets being so far off is that they are molded for people with round or oval heads, which I think is the majority of people. So they don't work for me, but they might if you have the appropriate head shape. Too bad the manufacturers don't have a way of telling consumers whether their helmets are round, oval or long oval.

    No place for a ponytail!

      Wanted to like this helmet but it just didn't work with a ponytail! Loved the optional vent though!
      I have the original Vertigo which is very ponytail friendly so I might go back and order the Vertigo 2.0!

      Fast

      • Familiarity: I've put it through the wringer

      I have had this helmet for a couple Months. I'm in Fl so I was concerned about the venting however it vents good for an aero. You can feel it cutting threw the wind with the vents shut and the air rushing in when open. A friend of mine felt he was at a disadvantage when I wore the helmet so much so, he went out and bought one also. He has not worn another helmet since. He rides with the vent closed only. I do open and shut mine all the time. I bought the Giro Synthe and will wear that in the heat but when it's cool or when riding with the fast guy's this is my helmet out choice.

      The Kask Infinity Helmet is not the same style per the picture if you look at solid black and the black/lime. Why is that?
