Safety first.

We freely admit that the first considerations some of us make when looking at helmets are about weight and aesthetics. With the Kask Vertigo 2.0 Helmet, we can get away with that, because underneath its lightweight and good lucks is a CPSC-certified safety net to catch us when we fall.

The Vertigo 2.0 is built on an internal skeleton, which is then fleshed out with shock absorbing EPS foam. The skeleton helps the helmet from shattering under impact, and the inner layer of foam is melded with the outer, polycarbonate layer for an additional boost to structural integrity. The three components — skeleton, foam, and shell — work together to diffuse the forces of impact throughout the helmet, taking a beating so your head doesn't. Kask has also included reflective elements on the helmet to keep you visible in low-light conditions for crash prevention.

In addition to the gel liner, the Vertigo 2.0 uses Coolmax padding throughout. Coolmax uses channeled fibers to wick moisture from your head for cooling evaporation, so it contributes to a comfortable fit and temperature. The pads can also be removed for washing, but Kask gives them an antimicrobial treatment to help limit the amount of washing they need. The eco-leather chinstrap is also washable in addition to being hypoallergenic and providing a non-abrasive fit, which can be refined using the standard ratcheting wheel and Kask's double pivot design. The Vertigo 2.0 includes a bag to keep it safe while it's not keeping you safe.

  • Internal skeleton for better impact performance
  • Up & Down adjustment keeps the helmet comfortably secure on your head
  • Coolmax pads with antibacterial treatment

bad design

  • Familiarity: I've used it once or twice and have initial impressions

Bad price....terrible design...look at the retention strap and decide if you can wear sunglasses....the you tube review cyclist is not even wearing sunglasses with this helmet....joke!

No room for sunglasses? Wtf?

  • Familiarity: I returned this product before using it
  • Fit: True to size

Really really wanted to like this helemt. Tried it on, felt great, looked good on my head. Then I tried it on with my Smith sunglasses (I forget the name but they are cycling specific) and the rails kept smashing up against the rear retention mechanism. I could wear my glasses with this helmet, but I could tell it would hurt after a while because I had to jam the rails underneath the retention mechanism so it pressed into my head. How the heck does a $250 helemt have this as an issue? My $100 Giro helmet doesn't...back to the drawing board. Another issue, there is a LOT of padding in this helemet, which probably doesn't do much for crashes since its the shell that absorbs the impact. I can see this getting really hot and nasty in the summer.

I have same issue. Only glasses that work for me are my Oakleys where I can shorten the length of the temple pieces. Also agree with next review that helmet is hot. However i do have the right glasses AND I'm always cold so I like this helmet. It looks the best of any brand on me, and it feels the most sturdy and protective.

Profuse forehead sweat maker

I have been using this helmet for several months now and deal with so much sweating from the forehead area that my glasses become useless due to blocked viability. Not what i expected from an expensive helmet. I have a Smith helmet with the honeycomb protection which has been my go to helmet for long distance warm rides. Its much more comfortable and there is ZERO problems with sweat. I average about 240 miles a week on my bike, so comfort is really important. Ask could do better. I'm not pleased!

Fits very snug - probably the most out of any helmet I've owned. It doesn't move around and the rear clip feels 'secure' below the head where most helmet clips lie.


My forehead hurt after the ride. I think it has to do with that thick padding on the front of the helmet. I took the front padding from my Giro and put it on there to try out on the next ride. From a crash standpoint, I get the thicker padding but not from a comfort standpoint.


Hideaway up/down rear clips. Great idea when you're storing the helmet.


Kind of a pain when you go to put the helmet on since you have to loosen it first to get it on your head.

Also, this weighs about 295g vs. 270g (but maybe the listed weight is based off a smaller size).

Aside from style, each plus has a minus

Good but...

  • Familiarity: I've used it several times

While I like the helmet, I found out the hard way there is a plain steel pin in the strap that has began to rust severely which has stained the white on the strap. I contacted KASK customer service and they said I caused the rusting by sweating too much and that I would have to pay to have them fix it. I would only recommend purchasing this helmet if a) you don't sweat, b) you never rinse sweat off your helmet with water or c) you never allow your helmet to come in contact with oxygen.

Good but...

Hands down my favorite helmet

  • Familiarity: I've used it several times

I have a few rides in with the Kask Vertigo 2.0 and I must say that it exceeds my expectations. I have worn Giro for many years and the do make a great helmet. The Vetigo 2.0 is just better in every way. Kask gets all of the little details right. I would definitely recommend purchasing this helmet.
Also, Justin Morgan and the rest of the customer service crew at Backcountry are amazing to work with.
So buy the helmet. Yes it's expensive, but it's your brain your protecting. When you do, buy it from Backcountry for the best price and best customer service!

What is the actual weight on the Large Vertigo 2.0? Thanks! I am trying to make an informed decision between this and another. My neck needs real numbers :-)

I saw on YouTube that you have the Kask Vertigo XC mtb helmet, but when I try to find it on your site, I can't.

Can you help?
Thank you, Jose

A Cut Rate Version of the Original

  • Familiarity: I've put it through the wringer
  • Fit: True to size

First, let me say that I've owned 2 of the original Vertigo helmets and they were/are great. Very stylish with first rate comfort and construction. The first helmet was also successfully battle tested last year after I smacked the back of my head on the pavement in a crash during a crit. My head was totally fine afterwards. So, I immediately (and gladly) forked over $300 for a replacement. I've recently changed teams and was in the market for another helmet to match my new team kit. Naturally, I decided to go with the Kask Vertigo 2.0. The 2.0...that HAS to be at least as good as the original, if not better, right?

Nope. First, Kask has downgraded the strap system. The leather chinstrap and up and down retention system are still there. But, the straps are basically the same as you'd find on a $50 helmet and the junction between the cheek and chinstraps is stitched together. The original Veritigo used a piece of molded plastic as the junction between the cheek and chin straps. When worn, these pieces rest perfectly and unobtrusively on the jaw bone. Kask has done away with this on the 2.0 and the step down in comfort is noticeable.

Also, on the 2.0, Kask has eliminated the tabs that keep the rear straps attached to the rear retention system. So, putting on the 2.0 now involves fidding with the rear straps to avoid tangling them up when the helmet is put on. A major PITA in a helmet at this price point. Why would Kask eliminate these tabs? I'm sure they couldn't have cost more than a few cents. Boggles the mind...

Anyway, I couldn't return this thing fast enough. Where the original Vertigo was stylish and offered first rate comfort and construction, the 2.0 is stylish and offers cut rate comfort and construction. If you've owned the original and are considering the 2.0, my advice is to forget it. You'll be just as disappointed as I am.

* Update - 4/7/2016: It's a long story. But, after checking out various other helmet options, I grudgingly decided to go back to the Vertigo 2.0. I'm glad I did because the helmet I received included the tabs in the rear retention system for attaching the rear straps. So, that takes away some of the sting at least. Adding a star to my review but still disappointed that Kask downgraded the straps themselves.

I know WAY too much about this helmet.

I returned mine as well! Your comments are spot on. You cannot adjust the yolk around the ears because the strap is stitched together. The straps on my KASK were so far forward they almost touched my eyes and there was no way to adjust the straps. KASK customer service was really bad. My head circumferance was smack dab in the middle of the medium size range and the helmet fit perfectly. When I explained this to KASK this was their response
"We have seen this happen a few times before, typically if the helmet is a size too big for the rider. This will cause the straps to sit further forward on the face. We unfortunately do not have something you can add to the straps to bring them further back. Perhaps you can try on another size at one of our dealers and have it swapped out where you purchased it depending on their return policy. We also recommend trying a Mojito or a Protone if this is an option for you. One other suggestion would be based on if you were riding low toward your handle bars or more upright, because this helmet is meant more for an upright rider. " So if you plan to use this $250 helmet be sure to stay "upright" on your bike. They also asked me to send them a picture of me wearing the helmet to show how the straps fit. I did and also sent them comparisons of how good helmet straps fit. They said they would get right back to me. Never heard from them again. Helmet returned. Excellent service from Competitive Cyclist as always. No questions asked.

It appears the Mojito still has that molded plastic between the cheek and the chin strap. Did you try the Mojito? I am replacing mine due to a crash and was thinking about the Vertigo, but your post gives me pause. Maybe I should just get another Mojito - it does fit me well and it certainly did its job.

nice helmet, fit wasn't for me

  • Familiarity: I've used it once or twice and have initial impressions

I typically wear a small in giro and bell. I bought the S/M and although the fit was "ok" it seemed like I had more space on the sides of my head than I usually do. I suppose I do maybe have a narrower head, if you have a rounder head this may be great for you. The retention system was excellent and very comfortable particularly the back of the head. I decided to return and exchange for another helmet that had different sizing that fit me just a little bit better.

The straps don't stay in the back pivoting system - are they suppose to?

No. I had an issue with this as well. I was told by KASK that there was a design change for 2015 and they removed the tabs that held the straps in place. It's terrible because you have to hold the straps in place prior to puitting the helmet on. I was also told that tabs may become available after the new year. Contact them to get on the list and they will let you know when they are available.

Unanswered Question

Is the internal shape the same as the Mojito? I have a round head (Asian), and heard that the Mojito is pretty round. Just wondering if Kask uses the same shape across al their helmets.

Hello Team
My fat head is 58.5 cm and I appear to fit in between Vertigo sizes. Based on your experience, what size Vertigo should I wear? Thank you.

Buy the Large. I bought a Mojito and with my size 58.5cm head it was simply too tight. My son is a 58cm and believe it or not -- the size Medium fits him. So my head might be slightly differently shaped but anyone with a "borderline" (58.5 to 59cm) head should consider buying the Large. So I'm now going to buy a Large Vertigo.

Can you park your sunglasses at the front of of your helmet? It would be great if you have a picture.

Yes, with my Smith Optics Pivlock V2Max. YSunglassesMV.

sweaty forehead

    I've been using this helmet for a few months now and it's working really well. There are a few points to mention though:

    1. I find that more sweat rolls down into my eyes and down my nose with this helmet in hot weather.

    2. As mentioned previously, there are issues with sunglasses. The ends hitting the rear adjustable part and nowhere to place them securely.

    Overall, the helmet is great. The ventilation is good and it doesn't weigh too much. If Kask can work on the two points above then it would be a really exceptional helmet.

    great helemt

    • Familiarity: I've used it once or twice and have initial impressions

    very light. rear strap comfy, built well. leather strap soft. as heard before glasses are hard to fit. they will hit rear head strap if too long or straight. once found the right recommend this helmet tho

    Cadillac of Helmets

    • Familiarity: I've put it through the wringer

    Wow. Very, very nicely made. Not sure I have ever seen a helmet that was 100% made in Italy, except maybe SH +. Pretty much every brand is made in China. Pricey is an understatement for this thing, but the craftsmanship is there. The fit is super comfortable. The "up and down" feature of the occipital skull adjusting strap/mechanism is very innovative as you can move that portion of the helmet way down the back of your head (almost to your neck), and work upward anywhere in between for the level of comfort you desire. The pads are super thick, anti-microbial, and of coolmax. They are attached perfectly. Not loose and sloppy looking like most other helmets. The inside of the up and down brace has gel padding squares as well. They are firmly affixed and not cheaply done. The side straps or "U" strap is perfect. without a stupid adjusting mechanism to get twisted, or to stick out, or to rub your ear. The leather chin strap is supremely soft, comfortable, and appears absolutely bulletproof. Totally overbuilt for what it is. Great job by Kask on this. The paint, fit and finish, and decals are absolutely flawless. The leather chin strap also has "made in Italy" proudly emblazoned on it as well, if you feel like showing off to your riding partners.
    As mentioned in the original Vertigo reviews, there is, and continues to be a sunglass interface problem. The ends of the arms and temple pads hit the front portion of the Occipital brace/adjustment band. I was totally panicked, and thought this was a deal breaker, for I cannot ride without sunglasses. However, I remedied this by simply snipping off about 3mm of the ear piece ends of my glasses with side-cutters. I know that you should never be expected to have to do this when purchasing a helmet, but I really like the Vertigo, and took a chance. Worked perfectly, but Kask needs to get a handle on this. These were 69.00 Tifosi glasses by the way. Not sure I would go that route with 200.00 glasses.

    As an update to this review, I have now logged many miles on this helmet. I upgraded to Oakley Split Jackets, and against what I advised everyone else, they fit fine with no interference to rear up down securing system. I still love this Helmet, and would not consider replacing it, but after reading that the original Vertigo had more features than the 2.0 I'm slightly annoyed that I paid more money for less features.
