A practical choice for commuters, recreational road riders and gravel explorers who want one comfortable, lightweight helmet rather than a dedicated race model.
The Kask Sintesi is built as an adaptable all-rounder for road, gravel, MTB and urban commuting. Its smooth, understated profile suits everything from weekday transport to relaxed weekend rides, while the 230 g claimed weight in size M keeps it pleasantly unobtrusive on your head.
Inside, an EPS inner shell works with a polycarbonate outer shell, CE / UKCA EN 1078 certification and KASK’s WG11 rotational-impact test. The Ergo Fit system gives you straightforward micro-adjustment around the head, with vertical and tilt adjustment helping you settle the rear cradle into a secure, comfortable position. Independent testing found the fit stable over road, gravel and commuting rides, including long days in the saddle.
The Blue Tech padding is breathable and treated with antibacterial and antistatic properties for comfortable regular use. The Sintesi offers useful airflow through its 13 vents, although riders who run particularly hot may prefer a more heavily ventilated helmet. There is also no dedicated place to dock sunglasses, so it suits riders who normally keep their glasses on or stow them elsewhere. Choose size L for a 59–62 cm head circumference.
