According to the product specialist

Pros
Equipped with the new Roc Loc ® 5-Plus fit system for even better adjustment of your helmet's fit.
Good-looking helmet that's aerodynamic and has great ventilation.
MIPS Spherical is integrated between 2 layers of EPS foam and absorbs the impact of a fall very effectively.
This helmet can also be worn with a ponytail.
The MIPS system reduces the shock of a crash substantially, increasing head safety.
Its compact shape and Aero Mesh panels create good aerodynamic capabilities.
The 26 air vents and the Roc Loc Air Fit System guarantee optimal ventilation.
The X-static Padding has antibacterial properties, making the helmet stay fresh for longer.
The specials slots allow you to easily put your cycling glasses on the helmet.
Lightweight - you almost don't even notice you're wearing it.
Good ventilation for such an aerodynamic helmet with 15 ventilation apertures.
Leather straps for extra comfort.
The upper part is reinforced with an internal plastic substructure, for better fall protection.
Thanks to the Octofit adjustment system and divider earband, this helmet can be adjusted very precisely.
Cons
The Roc Loc ® 5-Plus fit system feels slightly fragile when adjusting your helmet.
In addition to adding extra safety, MIPS also adds some extra weight to the helmet.
MIPS grants extra safety, but also makes the helmet a little heavier.
The Roc Loc Air adjustment system feels a bit fragile for a bicycle helmet of this grade.
Kask does not use MIPS, so that extra bit of security is missing.
The leather chinstrap takes some cycling trips to feel comfortable.
