With the Sierra MIPS Scott has a versatile bike helmet in its programme that is clearly aimed at sporty bikers. Whether gravel adventure, an after-work ride on tarmac or a trip on the single trail - the helmet is designed to cover a wide range of uses and combine comfort, safety and adaptability. The Scott Sierra MIPS aims to be a modern helmet for bikers who don't just define themselves by one discipline, but want to utilise the entire spectrum of the sport. To ensure that protection and comfort are always right, the developers have integrated the MIPS system, flexible adjustability and a well thought-out ventilation concept. In our test, we found out whether the Scott Sierra MIPS really works equally well for gravel bikes, road bikes and light off-road terrain.
The Scott Sierra MIPS is deliberately not limited to a single discipline. According to the manufacturer, it is equally suitable for cross-country, gravel and road. It is precisely this versatility that makes it particularly interesting for riders who do not want to limit themselves to one terrain. A removable visor emphasises this approach: with the visor, the helmet looks suitable for trail and gravel, without the visor it blends in visually with a classic road bike set-up. This flexibility can be a real bonus in everyday life, especially for commuters or multisport riders.
The centrepiece of the Sierra is the integrated MIPS system (Multi-directional Impact Protection System). This is a low-friction sliding layer inside the helmet that is designed to reduce rotational forces in the event of angled impacts. Such rotational movements are considered to be the main cause of concussions. The helmet also fulfils the European standard EN 1078 and belongs to PPE category II - a common standard for cycle helmets in sporting use.
A good safety concept stands and falls with the fit - and here Scott relies on its own Halo 270 Fit System. This allows fine adjustment around the back of the head and ensures a stable fit even on longer rides. Particularly interesting: the pads can be individually cut and adjusted. Predefined cutting lines facilitate fine-tuning to different head shapes - a small but nice detail.
With a weight of 341 grams (BIKE measurement, size L), the Sierra MIPS is in the solid mid-range of modern all-round helmets. The in-mould construction with polycarbonate outer shell ensures a stable yet lightweight design. For cooling, Scott relies on strategically placed ventilation openings that are connected to internal air channels. The result: continuous airflow even when riding slowly or on climbs - a decisive factor for comfort on long tours.
In practice, the compact design is particularly impressive. It ensures a snug fit without any wobbly movements - regardless of whether you are travelling on rough surfaces or at higher speeds on the road. The combination of low weight, good ventilation and customisable padding makes the helmet particularly suitable for long distances. It really comes into its own in changing areas of use.
The Scott Sierre MIPS is a no-brainer - just put it on and ride off. Whether I'm commuting, bikepacking on a gravel bike or on a cross-country evening ride: I always like to put on the compact Scott helmet. Its versatility should be a clear selling point for sporty bikers at the interface between MTB and road bike. For trail use, I prefer a more voluminous model. - Jan Timmermann, BIKE editor
