@ Dan
On your Italian website
http://www.dainese.com/it_en/motorbike a model is wearing the Horizon jacket and what looks to be pants made of the same material except for leather around the knees/slider area. And now that I look closer there is also leather in the butt-tocks area.

m - sorry was watching Forrest Gump last nite
Edit: After clicking one the of
+ signs, the pants in question have been revealed to be Horizon Pants. These would make excellent hot weather pants plus they have sliders. Can we get them on this side of the pond? And if so what is the damage?
