Overview
Is the Kask Sintesi the right do-it-all helmet for road, gravel, and commuting?
The Kask Sintesi in Sea Ice is the Italian brand's most versatile helmet, built for urban cyclists, gravel adventurers, and road riders who want one helmet that does it all. Construction follows Kask's MIT technology, wrapping a polycarbonate outer shell over the EPS foam liner across the top, base ring, and rear sections, protecting areas typically left exposed on budget helmets where foam can chip or degrade. Inside, Blue Tech padding is breathable, antibacterial, and antistatic, keeping you comfortable across long rides while resisting odor build-up.
The Ergo Fit retention system is purpose-built for the Sintesi, providing an excellent fit and stability across uneven terrain whether you are commuting through traffic or putting in long miles on gravel. Thirteen vents move air efficiently across the shell during hard efforts, and the synthetic leather chinstrap is comfortable, anallergic, and easy to clean. Total weight is 230 grams in size M. Tested against Kask's Rotational Impact WG11 Test protocol and certified to CPSC 1203, CE EN 1078, and AS/NZS 2063. The Sea Ice colorway is a soft, refined blue tone perfect for riders who want a touch of personality without the high contrast of brighter colors.

Good questions
Get to know Kask

There's more to Kask than this one product. Our Kask page has the full Kask lineup we carry and more about the brand.
Visit the Kask page →What is the Kask Sintesi best for?
It's positioned as a do-it-all helmet that handles road riding, gravel adventures, and urban commuting equally well. The combination of low weight, MIT shell coverage, Ergo Fit retention, and three-standard certification makes it a strong choice for riders who want one helmet for multiple types of riding.
How does the Sintesi compare to the Mojito 3?
The Sintesi sits below the Mojito 3 in the Kask lineup. It uses Ergo Fit retention instead of the more advanced Octo Fit, has 13 vents versus the Mojito 3's optimized vent system, and comes in two sizes instead of three. Both helmets share Blue Tech padding and WG11 testing, making the Sintesi the more accessible option without sacrificing safety.
What is the WG11 Test?
The WG11 Rotational Impact Test is Kask's proprietary alternative to MIPS, an in-house safety protocol that tests the helmet at five different impact points to evaluate performance against rotational impacts that are strongly linked to brain injuries.
Can I wash the Sintesi padding?
Yes. The Blue Tech padding is removable for hand washing or gentle machine washing, and replacement pad sets are available from Kask if the originals wear out over time.
