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.
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.
This helmet is highly aerodynamic yet also provides sufficient cooling during warm and long rides.
With MIPS, a helmet absorbs shocks from a fall better for increased safety.
When you don't want to use the visor, it can be removed.
With the Roc Loc Air fit system, you can adjust the fit until it's perfect for you.
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.
Kask does not use MIPS, so that extra bit of security is missing.
The leather chinstrap takes some cycling trips to feel comfortable.
In addition to safety, MIPS also increases the helmet's weight.
