Don't 'leaf' home without it.

What happens when one of the world's most sophisticated road helmet companies decides to dip its feet in the waters of mountain biking? The Catlike Leaf Helmet, of course. With 23 air intakes, cutting-edge construction techniques, and a weight match of 260 grams between the Leaf and the Whisper, the Leaf is set to take the mountain world by storm.

To achieve this, Catlike implemented multiple proprietary technologies from the road side of things. Like the Whisper, the Leaf 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. This design is not only a revolution in safety, but an integral aspect of the Leaf's, well, leaf-like weight.

Outside of safety, Catlike's goal is to provide you with a lightweight helmet that has ample ventilation. The Leaf's 23 air intakes are a good start, but Catlike didn't stop there. The Leaf features the same Dual Flow design that's found on the Whisper, which 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 air stream 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 Leaf, and eliminates the need for bulky construction material.

For adjustment, Catlike implemented its patented Multi Positioning System Evo (MPS eVo) 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. For preparation against the creepy crawlies found on the trail, the helmet also includes an Anti-Insect Net to block out any unwanted visitors to the helmet. And speaking of blocking things out, the Leaf includes a large removable visor to keep your field of vision unobstructed and resolute.

The Catlike Leaf Helmet is available in the sizes Medium and Large and in the colors Matte Black, Matte Black/tree, Matte Lime, and Matte Red.

Good looking helmet

Well designed helmet- sleek, not as tall as Giro helmets, which is nice. I am between a S and M in Giro helmets, and the M in this Catlike Leaf fits great. The retention system is easy to adjust and comfortable. Super lightweight, too.

Great CC helmete

  • Familiarity: I've put it through the wringer

This helmet is light and airy! I wear it on hot days or Cross Country rides.
Love the fit!

Wondering why Catlike doesn't make the...

Wondering why Catlike doesn't make the Leaf in Small, Medium and Large. I think the shape is right for me, but I'm concerned because I'm at the smallest end of their "S" (or "M") sizing, and wonder if it'll be too big. Is the Leaf adjustable down to the smallest sizing, for real?

Best Answer Responded on

Not quite sure what influenced the decision to only make this in two sizes. If you are at the bottom end of the sizing scale for the medium but are within the sizes listed the helmet will adjust to your head and will fit. If you are right below the sizing that is listed then the helmet likely will be too large. Feel free to contact our gearheads via live chat or by calling 1-800-409-4502 for further help sizing this helmet.

"I like your helmet"

  • Familiarity: I've used it several times

Every time I wear this helmet I get a complement on it, be it on the trail or at the coffee shop. I think the thing that really makes this helmet stand out is the red color - it has a matte finish, but the color is so vivid you just want to touch it to make sure your mind is not deceiving you.

I really love this helmet, it is comfortable and it super easy to adjust in the back as it has a turn retention system. At just over a hundred dollars this helmet is a great choice!

Great hot weather helmet

  • Familiarity: I've put it through the wringer

I commute in Hawaii, and this helmet is great. It has venting as good as any I have tried (many.) It is also super light weight and barely noticeable on your noggin. Great helmet, looks good.

Great helmet at a great price!

  • Familiarity: I've used it several times

Decided to go with the Catlike after researching helmets for years it seems! Seemed like the best combination of weight, style and price. I bought it at the same time as the Giro XAR. At first fit, the Giro seemed better, but after adjustments, you could tell the Catlike was a winner. More contact points and more ways to adjust (it comes with extra pads). The bug screen over the holes is a bonus. In the days of high priced helmets (the new Smith?? Although it does look sweet) this is a solid choice.

If in between sizes, go down. I was L size (right on the low end), but got a M and was happy I did.

My head is 57.5CM and I've tried the large which is too big. Since the small max size only goes up to 57cm I'm concerned that will be too small (especially if I want space to wear a thin cap beneath in winter. Any advice as to whether there is enough wiggle room that the small will work? Strange they don't have overlapping ranges in their sizes like other manufacturers...

Hey John,

I would recommend that you try a Medium - I think this will be the most comfortable fit for you and it will give you a little bit of room for a hat. This medium fits really similar to a medium bell, giro, and poc.

I have a 58cm head, what size do you suggest?

A 58cm measurement is on the bottom end of a size Large.

Medium 54-57 cm
Large 58-60 cm

Anyone have any issues with wearing sunglasses with this helmet? It seems to be a common complaint with the All-Mountain/Enduro style helmets.

Responded on

Cam, Enduro helmets tend to have greater coverage than road or XC helmets and might infringe on melon and mug space for glasses. But below there are 5 positive reviews of this brain bucket without a single mention of sunglasses. I think you can be confident in using sunglasses with the Leaf. If they do end up causing problems we have a killer return policy. Hit me up with any other questions.

Responded on

There is no problem wearing sunglasses with the leaf. The only gripes are the chin strap canes back against the neck and so you have to fiddle with them to get further out under the chin. The cool max pad in the front will fill up with sweat and if your forehead presses against it the sweat will come pouring out on your glasses and face. I wear Oakley fives or piv lock v2s and have not had a problem with either fitting. This is a great helmet and it looks different from all the trabecs, and fluxes everyone seems to have right now.

I think it's the best helmet I have. I like the knob adjustment in the back and visor. Handsome appearance too.
Bug net will come in handy in the spring and summer.

Fits great

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

I don't have this helmet yet but I did try on at the bike shop. Thought I would at least let others know it fits similar to giro just better. More contact points to make more comfortable rather than giros 2-3 contact points leaving marks on your forehead, etc. I tried Bell helmets and I know other say the same time...either your a bell head or giro head. This Leaf will be my next helmet!

Best Helmet yet.

  • Familiarity: I've put it through the wringer

Love this thing - I'm picky about helmets and seem to have a hard time fitting them correctly. The leaf is super adjustable, light and ventilated. The quick adjustment dial in the back works super well & I can only assume (as evidenced by the lack of wasps in my helmet) that the bug screens are doing their job. I tried both the Poc Trabec and the Six Six One Recon during my purchase & this one seems light year better.

I have a pretty big head & always wear a large... the large in this helmet is perfect.

Light as a Leaf... Almost

  • Familiarity: I've put it through the wringer

This was purchased for my husband and this is what he has to say-

The Leaf helmet is perfect for long XC rides because the ventilation is amazing and it is incredibly light weight while still offering protection. Compared to my old helmet, the Leaf feels like a light breeze.

Great helmet

I have had this helmet out on the trail three times now and it has been great, I completely forget I'm wearing it, vents very well and is very light weight. I have been wearing a fox flux up until I got this helmet, the fox fits great just a bit heavier and doesn't vent as well. I wear a giro aeon on the road bike and the leaf feels very similar in weight and ventilation.
