It depends on how cool YOU think it is? Justification depends on how well you can convince yourself to drop some coin on any equipment.

Seems that you really want that Orbea helmet, though! I don't blame you, that is nice looking and looks different from a lot of the other helmets out on the road. There are very few helmets that does not look generic. A few I can think of would be Catlike with it's Swiss cheese-like desing, the Specialized Echelon through Prevail, with it's mouthport and that Orbea.
