ideas for perfume for a pre-teen boy?

My son (11 years) are into perfums. He's been with me to perfume stores his whole life - and my obsession has been passed on... (ups)..

Up until now, he has been allowed to borrow some of my small testers from time to time, but for this christmas I will give him a full bottle.

But what to give him? It shoud be age appropriate - and not an ambroxan bomb (I hate that)! Any ideas?
