This product has been selected to feature in recommends. That means it's not just scored well, but we think it stands out as special. Go to recommends

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.

The Kask Sintesi is one of the best cycling helmets out there. It's light, comfortable, looks good, and is suitable for all styles of riding, from urban commuting and road cycling to gravel. It includes a number of useful features for an attractive price, and there are plenty of colours to choose from.

Its construction is based around an EPS (expanded polystyrene) inner and polycarbonate outer shell, with breathable, antibacterial and anti-static Blue Tech padding inside.

As well as meeting the usual standards, CE EN 1078, CPSC 1203 and AS/NZS 2063, the Sintesi has also passed Kask's own WG11 Rotational Impact test, its alternative to Mips. If you're not familiar with them, our Kask WG11 vs Mips feature looks at how the two technologies compare.

The Sintesi comes in two sizes, medium (52-58cm) and large (50-62cm), with a dial at the rear for adjusting the fit. The shape is neither narrow nor round, and I found it exceptionally comfortable, with the internal cradle cupping my occipital bone beautifully. This led to the helmet not only feeling comfortable, but also supremely confidence-inspiring in terms of stability – this helmet was going nowhere once dialled in, yet without needing to grip tightly.

With 13 generous vents, there were no issues with overheating, and the air is channelled very effectively by those vents.

The interior padding is comfortable and pleasantly breathable, with any moisture drying out nice and quickly. This padding has an antibacterial treatment, which should enhance its lifespan, but a replacement pad kit is also available.

At just 237g this helmet is in the weight territory of performance road helmets rather than the often beefier commuter lids. It certainly felt unobtrusive to wear; it's light but still inspires confidence.


Compared with a variety of helmets straddling the recreational/commuter sector, it undercuts them on price and weight.

For example, at £100 the Met Vinci, which Stu tested a couple of years ago, comes close but weighs 264g, while the Smith Persist now costs £99.99 (up from £94.99 when Janine tested it last year) and weighs 300g.

The Cannondale Intake MIPS is £10 less at £80, but a heftier 284g, has less ventilation and fewer colour choices, and in his review, Neil wasn't impressed with its lack of adjustment.


Overall, if you're looking for a stylish lid for all types of riding, it's hard to find fault with the Kask Sintesi. It offers a comfortable and secure fit, decent venting and low weight, all at a very reasonable price.

Thank heavens the lining is anti-static, I simply won't wear any other sort.  Years, I tell you, years I've been searching for a helmet which isn't prey to the vagaries of the electro-magnetic spectrum.  At last, I'm free.  Into the sunset I ride, not a static affected hair on my head ...... 

( To be continued when they let me out of here.)

I got one of those static-inducing helmets - it was literally hair-raising.

Nice review. Can you store sunglasses in the front vents?

Sriracha replied to littlemig | 1 year ago

I think you've hit the nail on the head with your line of questioning. We wear helmets ostensibly to save us from head and brain injury, a conceit few of us believe with much conviction.

And yet there is so much more that a hat, if we must wear one anyway, could do. I'd like mine to:
Keep the bugs out
Stop my pate (and tops of ears) getting sunburn
Shade my eyes from the sun
Keep my head warm in winter, yet cool in summer

I'm sure there are other things too - like sunglasses holder.

Yes Indeed. I like to attach not only a headlamp with separate battery fitted at the back of the helmet but a gopro too. So that's three mounting points I always add to my helmets. The battery is able to charge the gopro and the headlamp at the same time but requires an adapter for that so I fix some velcro for the adaptor to fit to too.
