Refurbished reasons: The helment doesn´t have its original box, packaging and tags.An amazing allround helmet suitable for all kinds of mountain biking. This model is equipped with Mips, a technology that reduces rotational forces on the brain The Dissenter is a bang for the buck helmet, benefiting massively from our research and development on the high-end helmets. A single-piece polycarbonate shell, in-mold technology and Sweet Protection´s proven geometry combine to provide all-mountain coverage in a low weight, low profile package. This model is equipped with the Mips Brain Protection System, a low-friction layer solution designed to reduce rotational forces transferred to the brain.MIPS - Multidirectional Impact:- The MIPS Brain Protection System is a helmet-integrated low-friction layer is designed to reduce rotational motion transferred to the brain from angled impacts to the head.EPS-liner:- The advanced EPS (Expanded Polystyrene) Liner is constructed with variable bridge- and channel volume in order to optimize the overall impact protection performance.Occigrip Turn Dial:- Makes the helmet easily adjustable with a low volume mechanism. The Occigrip construction provides a firm and comfortable fit and prevents the helmet from rolling on your head. Adjustable on the fly in both reach and height.Comfort Pads:- Molded Comfort Pads with soft and comfortable foam wrapped in an no anto allergenic for environmental reasons and moisture wicking fabric. Each helmet is delivered with two pad thicknesses for easy fitting.STACC Ventialtion Falconer:- Superficial Temporal Artery Cooling Channel (STACC) is a front vent, an internal channel and an exhaust vent that cools down the temporal artery without exposing your temples which is the most vulnerable area of the head.DOV Ventilation:- Digitally Optimised Ventilation is optimised through digital air flow simulation. This ensures the air flows well through vents and internal channels at different speeds.Feature:- Allround helmet- Comfortable- Highly ventilated- Occigrip- Lightweight
