Limar Ultralight+ Road Helmet



Very light and airy lid that will be appreciated on the climbs – ours scuffed easily though

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

As the name suggests, the Limar Ultralight+ is a superlight helmet that's also super-comfortable and keeps you very cool.

Limar claims it's the lightest bike helmet in the world, with this medium size weighing in at a tiny 175g and the large 210g. This low weight plus the 22 air vents would have been appreciated by the Astana Pro team on the climbs of the Tour de France recently, including fifth-placed finisher Fabio Aru.

The helmet comes with a removable visor (Limar also says it's suitable for mountain bikers) and a little rear light that attaches to the retention dial, pushing the weight for our medium up to a still-impressive 206g. The light isn't a replacement for your rear light, but it's good enough to use as a day-light or just extra visibility.

George recently reviewed the Ultralight's slightly heavier cousin, the Superlight, and commented that he would prefer it if the bug net mesh could be removed. Here, a mesh bug net covers the front seven vents, and personally I didn't find it a problem, practically or aesthetically; it did the job on my rural training rides, so I will disagree with George and say I'm pro bug net!

I found the general shape and fit of the inner to my liking, although it does feel a bit high on your head when you first put it on. As soon as you're away you hardly feel like you're wearing a helmet at all, and the padding both inside and on the chinstrap kept me comfortable on test rides of up to four hours.

The dial can be adjusted easily on the fly, and it's a good size which makes this a breeze. Speaking of breeze, you get plenty through the 22 air vents in the Ultralight+, which is great for climbing and hot days. The antibacterial pads inside do a great job of draining sweat, and I never found the helmet held much moisture when using it the day after a hard evening ride.

The only actual issue I had was that the Ultralight+ has scuffed quite easily in the month or so of testing, so handle with care. Otherwise, it's a thoroughly lovely helmet to ride in, that looks good and is easy to adjust on the go.

Some might have concerns with the helmet's ability to protect, with that ultra-light weight; it has, of course, passed European safety standards tests, and so should provide as good a good level of protection in the event of a fall as any other helmet passing the tests – in fact Limar says it's one of the few brands whose products conform to all three international safety standards, CE EN 1078, AS/NZS 2063: 2008 and CPSC 16 CFR 1203. It's worth pointing out that the latter two – the Australian and US standards – are some way tougher than CE EN 1078 certification mandatory for helmets sold in the European Union. Of course, for some the whole subject of current helmet standards and how useful they really are is up for debate, but that's something with implications for nearly all performance cycling helmets.

Tell us some more about the technical aspects of the product?

Sizing system: Competition+ system with height adjustment

Pads: Antibacterial pads

Visor: Removable visor included*

Rate the product for quality of construction:

Good quality antibacterial pads are never soggy the next day, straps and dial are built to last, pleasing shape.

Rate the product for performance:

Plenty of venting to cool you down on climbs or in hot weather.

Rate the product for durability:

Ratchet dial and straps are nice and strong, but there are a few scuffs on the top after a month's use. The rear 'spoiler' flexes when you push it with your fingers, so I suspect that could be damaged if you're careless.

Rate the product for weight (if applicable)

If we're assuming that lighter is better, you can't get any lighter than this currently so of course it's excellent in this respect!

Rate the product for comfort (if applicable)

Dial is non-intrusive, straps have a nice bit of extra padding under the chin and inside it's very comfy indeed.

Rate the product for value:

It's about what you'd expect to pay for a top end helmet, though you can pay more, and the handy back light that fits onto the dial adds value.

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

Very well – for hot days and hilly rides it would be my go-to helmet.

Tell us what you particularly liked about the product

The comfort and weightless feel on the head and how quickly it drains sweat.

Tell us what you particularly disliked about the product

It has scuffed quite easily, which is a bit disappointing on a £160 helmet.

Did you enjoy using the product? Yes

Would you consider buying the product? Yes

Would you recommend the product to a friend? Yes

Use this box to explain your score

It's a high-end helmet for the spring and summer months (your head would get rather chilly in cooler temps), so if you can afford the luxury of having multiple helmets, I'd recommend it. I have noticed the helmet has scuffed quite easily already, and the material on top bends, which could affect its longevity. For those reasons I'm giving it a 'good' rather than a 'very good'.

Arriving at in 2017 via 220 Triathlon Magazine, Jack dipped his toe in most jobs on the site and over at eBikeTips before being named the new editor of in 2020, much to his surprise. His cycling life began during his students days, when he cobbled together a few hundred quid off the back of a hard winter selling hats (long story) and bought his first road bike - a Trek 1.1 that was quickly relegated to winter steed, before it was sadly pinched a few years later. Creatively replacing it with a Trek 1.2, Jack mostly rides this bike around local cycle paths nowadays, but when he wants to get the racer out and be competitive his preferred events are time trials, sportives, triathlons and pogo sticking - the latter being another long story.
