Cool speed.

At its core, a helmet's purpose is fairly transparent -- avoid a trip to the hospital after a crash. However, every helmet maker takes different paths to achieve this. And with rigorous certification systems, you can be assured that most helmets will generally protect you, but the question remains -- what levels of comfort are you sacrificing for safety? With the Catlike Whisper Helmet, the answer is none.

To achieve this, Catlike implemented multiple proprietary technologies. The Whisper uses a process called In Mold, where the outer and inner layers of the helmet are molded to become one piece. This process increases impact resistance, and improves diffusion of crash energy. For crashes where the back of your head takes the brunt of impact, Catlike incorporated its Low Nape Protection towards the lower rear structure of the helmet. For additional rear protection, the helmet uses a Crash Energy Splitter design that distributes crash energy throughout the helmet, and assures an even absorption of impact along the air intakes. This design is not only a revolution in safety, but an integral aspect of the Whisper's feather-light weight.

Outside of safety, Catlike's goal is to provide you with a lightweight helmet that has ample ventilation. The Whisper's 39 air vents are a good start, but Catlike didn't stop there. The Whisper features an exclusive Dual Flow design that utilizes large frontal air intakes that connect from the helmet's fore position to the oversized exit vents at the rear. Dual Flow creates a constant airstream through the helmet, and thus prevents overheating. This design also limits the material needed for construction, which would be a major safety issue for most manufacturers. However, Catlike uses a patented technology that they call an Airtube System. This system uses air-filled hollow elastic tubes that create an inner mesh within the helmet. This system reinforces the open design of the Whisper, and eliminates the need for bulky construction material.

For adjustment, Catlike implemented its patented Multi Positioning System (MPS)at the rear of the helmet. Essentially, this system allows the adjustment of the rear section of the helmet in multiple dimensions. So, with one retention adjustment, you can change the position of the helmet's rear both up-and-down and open-and-close.

The Catlike Whisper Helmet is available in the sizes Small, Medium, and Large and in the colors Green, Matte Black, Matte Red, and Matte White.

This helmet was nice but not for long

  • Familiarity:I've put it through the wringer

Helmet is relatively light, sits on the head OK. Be sure to take note of the shape of the opening as the medium fits my head very snugly and would tighten during exercise. Overall I liked the helmet but the padding wore out and back of head retention broke after 1 season (maybe 160 hours?) of riding. Side note: There is a red tail hawk nearby that likes the shape of this helmet and I found that a bit concerning.

Great for road and mtb

  • Familiarity:I've put it through the wringer

I wore this helmet for both road and trail. It always kept my head nice and cool when going hard. I believed it saved my life after being hit by a car while traveling at 30mph. Helmet is toast, but my brains are still in my head. I plan to get another one once I'm up and riding again.


Favorite Helmet of All Time

  • Familiarity:I've put it through the wringer

I've worn a lot of helmets, and I own several still, but I haven't worn anything but the Whisper since I first got it almost two years ago. It's well vented for summer and accommodates a cap for winter. I've got a hard-to-fit alien head, and this is the only low profile helmet that hasn't bobbed around once or given me trouble I've dialed in the fit. The harness system is really nice and accommodates ponytails. Overall, this is a really attractive, functional helmet. that's holding up really well over the years!

One of my favorite cycling related items ever.

Favorite Helmet of All Time

Don't forget the sunscreen

    Bought this as a gift, light weight and plenty of venting.
    Remember to apply your sunscreen if you have a limited quantity of hair up top.

    • Familiarity:I've put it through the wringer

    This was my first Catlike and I have had it 2 summers and 1 winter season. I buy a new helmet every 4 years or so. I have ridden various Lazer, LAS, Bell and Giro models over the years. The helmets that sit closer to the head seem to be poorly ventilated and hotter, regardless of what the helmet makers offer as far as hype. This helmet was/is the coolest and most well ventilated helmet I have ever owned. It does leave a little more space between the scalp and ventilation channels so it appears a little larger than some when worn. In winter it will fit my helmet liner with no trouble if I loosen the rear retention system slightly. Would definitely buy it again. Can't comment much more than the others on crash protection or fit (mine was great but I have never had a poorly fitting helmet).

    Saved my life!

    • Familiarity:I've put it through the wringer

    I bought a Catlike Whisper Plus Deluxe Helmet from Competitive Cyclist in January 2013. I was hit from behind by the extended side view mirror of a truck last Tuesday. I landed on my head and shoulder first and ended up with a concussion, two fractures of my pelvis, two fractured ribs, a separated shoulder, a large hematoma, lots of road rash and assorted other injuries. My helmet was cracked in seven places. When I arrived at the ER and my CT scan films had been developed, the head trauma doc picked up my helmet, looked both it and me over and said "There's no question, this helmet saved your life!". I should also mention that this helmet fits me perfectly, has the best peripheral visibility and ventilation of any helmet I've ever owned, is the lightest helmet I've ever owned, was extremely comfortable and had stood up to almost 18 months of hard riding prior to my accident. Until I landed on it, it was in perfect condition. I'm buying another Catlike helmet right away, even though I won't be able to ride a bike for another 3 months. During my three days in the hospital, my helmet sat on a shelf in my room and many doctors and nurses picked it up, examined it and told me how lucky I was to have been wearing such a well made helmet. It more than did its job.

    Saved my life!

    Just wanted to add that since I wrote my comment I've bought a Catlike Miximo hemet. I won't be able to ride a bike again until mid-September but I've tried it on, played with the settings and changed out the side pads to one size thicker. It fits very well and seems to be even lighter than the Whisper. I really like the new height and ratchet tightening adjustments. Can't wait to use it on the road.


    Super fly!

    • Familiarity:I've put it through the wringer

    Picked up one of these after my noggin' busted a Bell Sweep. I really liked the way the red looked in the picture, and it's even more electric in person! It's like a matte, bright red. Looks super fly!! One strap is grey...not red.

    I wore a M in Bell, and took a gamble with a L in this one after reading various comments about it fitting too big/too small. It isn't too heavy, and, I'm noticing the benefits of the plethora of vents as it heats up here in North Cackalacky. It fits a little differently than the Bell, as it sits a little differently on the head, however, I've found it offers more in the way of peripheral visibility and what not. Doesn't seem like there is a lot of padding, but, kind of like a minimalist saddle these days, it's got all you need without the bulk. The pads wick well and are nice and soft.

    Final thoughts...super ventilated, good looks, comfy, and not too many around!


    Didn't Last Long

    • Familiarity:I've put it through the wringer

    Rode the helmet for one year and it proved to be not very durable. All of the padding separated and fell apart, and the patented "Multi Positioning System (MPS)at the rear of the helmet" broke. The helmet gets two stars because it has great ventilation and it is light. However, I have had to replace it in less than a year.

    well damn it, you better not take advantage of that awesome warranty offers :/


    It Fits Me!

    • Familiarity:I've used it several times

    I think helmets are probably the most personal piece of equipment, some folks seem like any helmet fits just fine and others of us can't seem to find anything just right. Giro and Specialized both kinda fit me but Bell, LG and Lazer are a totally different story. The Catlike is by far the most comfortable helmet I've worn. As far as venting is concerned I can't tell any major difference from one brand to another, if you buy a quality helmet they all seem to vent about the same. So for me its all about fit, that said I think the Catlike looks cool.

    I went down in a local crit at 32mph, helmet skull didn't. I've ordered another.

    Pro Ventilation

    • Familiarity:I've used it several times

    Got a sweaty dome? Suffer from a soggy noggin? Step right up folks and plunk a Catlike Whisper on your head. I busted up my last helmet crashing into a bollard so I needed a new lid. After some research and reviews (Thanks Backcountry for the cool video review) I picked the Catlike. I'm extremely impressed by the fit, the weight, and the ventilation. It fits better than your favorite pair of jeans. It's virtually unnoticeable (unless you can feel a butterfly resting on your follicles) when strapped on. It's like wearing an industrial evaporative cooler, minus the big square metal box and the bulky water pump. And... the colors are pretty bad-#$$.

    On to the downsides... minor as they may be. The helmet industry hasn't adapted concussion-reduction standards, therefore the Whisper doesn't have that feature. A guy can dream. Wishing aside, it's on the expensive side, but you do get what you pay for.

    Pro Ventilation

    Wondering what the difference is between...

    Wondering what the difference is between the "Whisper" and the "Whisper Plus"? Thanx!

    I have both models and i have the same question.

    Best Answer

    I believe they're identical except that the Whisper Plus allows for a removable peak if you want to use it for mountain biking.

    Second times the charm

      I owned a Whisper briefly in 2011 and loved the fit and style but the ratchet broke after 2 weeks so I returned it. For 2013, the Multi Positioning System (MPS) is much improved and shows no sign of breaking after a couple of months of consistent use. In addition to being light and having good ventilation, the fit is great (I have a small) and doesn't make me feel like I look like a bobble head. My only complaint is that the plastic ring that holds the ends of the chin stap broke almost immediately. Not a big deal but its the only reason I didn't give it 5 stars.
