Limar Air Pro Aero Road Helmet

Tell us what the product is for

Limar says that the Air Pro is the latest development in a quest to push the envelope of safety and performance to its limits. It has been analyzed, tested, and developed in collaboration with the Astana Pro Cycling Team. This research and development doesn't come cheap, meaning that the Air Pro is likely to be used by riders who don't mind paying for marginal gains.

Limar has this to say about the Air Pro:

At 1st glance the Air Pro doesn't look like an aero helmet.

The design challenge was to design a fully vented helmet that kept the rider cool on the hottest of days and still worked aerodynamically.

Usually when you put a conventional fully vented helmet in the wind tunnel the vents just disrupt the air because they are there to let heat escape.

With the carbon coretech technology in the Air Pro we designed a fully vented helmet that works in the wind tunnel as well as keeping you cool.

The Air Pro is the most technological helmet on the market today and it enabled Astana to have a distinct advantage on the hottest mountainous days in the saddle.

CARBON CORETECH -

We have exploited the unique properties of carbon, coupling them with eps, to realize a maximum resistance core with minimum thickness.

Two structural wings merge with the side ribs of the shell, creating a highly performing cage in terms of safety, aerodynamics and ventilation.

From Limar:

TECHNOLOGY: Triple shell technology, in-mould carbon/eps double frame

AIR VENTS: 20 air vents, 8 longitudinal inner channels for extreme ventilation

SIZING SYSTEM: AirFit-System with vertical and horizontal adjustment and webbing connection

PADS: Antibacterial and washable comfort pads

FIT: Pro

SIZE (CM): S (53-56), M (54-58), L (57-61)

WEIGHT (G): S (230), M (250), L (270)

The use of a carbon core coupled with eps helps the Limar in terms of ventilation and aerodynamics whilst keeping weight down. We've seen it before with the MET Trenta 3k and it results in a high performing helmet, albeit at a cost.

Ventilation was excellent and I'm happy to accept the aero claims as they seem reasonable.

According to Limar's size guide I'm right in the middle of a medium. It was plenty long enough but too narrow. Try before you buy.

At 233g it's among the lightest claiming to give aero benefits as well.

The pads are well placed and comfortable and the rear retention system is well designed. The straps avoid the ears well, but the helmet is designed for someone with a less rounded head than me.

It's a pro-level aero helmet. You can, of course, buy helmets that offer the same level of protection at a fraction of the price.

How easy is the product to care for? How did it respond to being washed?

It's easy to wipe clean and won't stain easily; the pads are removable for hand washing.

Tell us how the product performed overall when used for its designed purpose

The ventilation is excellent and the helmet is very light. The fit let it down for me; try before you buy.

Ventilation.

Tell us what you particularly disliked about the product

The price, and the fit.

How does the price compare to that of similar products in the market, including ones recently tested on road.cc?

Priced at £229.99, it's among the more expensive helmets out there. Many at roughly this price come with MIPS technology, although the £220 Catlike Kilauea and £265 MET Trenta 3K Carbon that we've reviewed don't.

Use this box to explain your overall score

Although the helmet didn't fit my head shape, the low weight, excellent ventilation, and claimed aerodynamic benefit are very appealing features. However, it's more expensive than others that do a very similar job, at a similar weight. It's good – but try before you buy.
