According to the product specialist

Pros
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.
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.
Excellent finish quality.
Lightweight helmet at just 198 grams for a size M.
Well ventilated because of the 21 large vents.
Cons
Kask does not use MIPS, so that extra bit of security is missing.
The leather chinstrap takes some cycling trips to feel comfortable.
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.
The white straps of the helmet can easily look a little grimy.
The straps are a little inflexible.
