YMMV Review

Limar is an Italy Company that has been focused on Helmets since 1986. I noticed them for the first time in the 2003 Tour de France. At that time, I was just starting to get into cycling, and they were the helmet sponsor for some of the teams in the race. Fast forward a couple of years now and I was able to do a review of one of their helmets. I also am reviewing a pair of sunglasses that will get posted a little later.

Helmet on from the Front


I tested this helmet only on the road. I do not have the visor attachment but do not necessarily need it to ride trails. Due to the time of year I ended up not riding much trails. I also used the helmet on some of my commutes.

Sustainability (10%) ☆☆☆☆☆

Weight (30%) ★★★☆☆

The Carbon Ultralight is made to be one of the lightest helmets in the world.

Helmet on from the Side

The helmet is made using an in-mold construction method. In-mold construction is a manufacturing technique where the foam interior liner of the helmet is “blown in” while the hard exterior shell is still in the manufacturing mold. In-mold helmets tend to be lighter and have more venting than traditional methods. The helmet has a one-piece monoshell with a carbon insert. While the Limar website claims the helmet to be 200 grams, my measurements had it at 255 grams, which is quite a bit heavier. I believe that in order to comply with the safety standards in the US the helmet had to be made heavier. Unfortunately, this brings the weight up into the average weight for race helmets.

There is a total of 22 vents for air circulation. The front half of the helmet has a built in mesh insect net . The helmet uses a bidirectional ultralight sizing system. This system is a combination of lightweight webbing and a turn dial sizing wheel to optimize the fit. The helmet comes in two models: MTB and road. The main difference between the two is the included visor. I tested the road model, but it looks like you can use the visor on it as well if you choose to purchase it separately. Within each model there are several colors to choose from. The helmet also comes in two sizes: medium and large. The padding inside the helmet is washable with an extra set available.

Helmet on from the Back, Note the Twisted Strap Inside

I was not able to find any information on the Limar website about any use of green or sustainable practices. It does not mean they do or do not use them, but I cannot find anything, so I gave this a zero for sustainability.

Fit ★★½☆☆

Adjustability (20%) ★★★☆☆

Head Sizing (30%) ★★☆☆☆

Padding (25%) ★★½☆☆

Strap Comfort (25%) ★★½☆☆

I was a bit disappointed with the fit of this helmet. I do not think here is anything necessarily wrong with it; the helmet just did not seem to be the same shape as my head. Some of this issue may be my head. =) I tested the size large as I was just bigger than the medium on the size chart, and it felt too big. I measured my head to be 57 cm but think the medium would have worked better. Especially on the sides, there seemed to be extra room there. I could make the helmet shake back and forth even when I had it secure on my head. The helmet does have a good fit system. The straps are similar to other helmet’s straps and I like the dial fit systems better than other retention systems. All you have to do to adjust the fit is turn the dial, one way or another. In the back where the straps go around they pass through a small loop that seems to get twisted up easily. You can see this in the picture where you are looking at the back of the helmet on my head. The straps are twisted slightly inside.

Fit Dial System

The straps are as expected against the skin. There is also a bunch of pads on the inside that can be removed and washed if needed. Apart from being a bit loose on my head, the helmet felt good. I was not able to try a medium on; this may eliminate the fit issues I was having. If I do ever get a chance to do so I will make a comment on here.

Performance ★★★☆☆

Breathability (30%) ★★½☆☆

Protection (50%) ★★★☆☆

Versatility (20%) ★★★☆☆

The Limar Carbon Ultralight Helmet has 22 vents for breathability. They do a decent job at keeping your head cool during a ride. I did not notice my head being too hot or cold when wearing the helmet. The front vents all have built in bug netting. This netting keeps bugs from getting into the helmet which is quite annoying I must say. The only problem I have had with this netting is that it is permanent.  I was not able to use my helmet light while commuting with this helmet as the strap connects through the vents and with the net in place there is no way to pass the strap through. This helmet is not designated as a commuter helmet but having that option would be nice.

Built-in Bug Nettting

The helmet does have all the safety requirements needed. This is mentioned a little above as this is the reason the helmet weighs more than claimed. I have not gone out and tested how well the helmet truly protects my head. I will assume that their tests are accurate as I do not like to crash if I do not need to. I am a bit worried on how much the helmet does move on my head due to sizing issues, hopefully that will not affect the amount of protection it gives my head if I were to crash. The Carbon ultralight can be used for both road and MTB riding and has visor options if you have the road version like I do. I like to wear a billed cycling hat under my helmets so off road, I did not need the visor.

Removable & Washable Padding

Overall ★★½☆☆

Overall, the Limar Carbon Ultralight Helmet was just average in my book. I had some fit issues, which may be due to my head or that the helmet is made for rounder heads where mine is skinny. If the helmet fit my head a little more proportional I probably would have liked it a little more. I do not think it would have greatly influenced the rating though as I was also disappointed in the weight. I expected the helmet to be around 200 grams and was disappointed with the actual weight being 255 grams. I understand why this needed to happen in order to meet the US safety requirements, but I have also seen other helmets do so and stay down in the ultralight range. The fit system works well, and the venting is decent, if you find it fits your head well it may be a good option for you. The helmet says it retails for $250, which is steep considering the weight is higher on the US model. Most of the sites I have checked out had it for cheaper than this. As always, your mileage may vary.

  • Crash Replacement Program
  • Dial Fit System
  • Bug net in front vents


  • Did not fit my head shape well
