Boyfriends 17th birthday present ideas?

So my boyfriends 17th birthday is coming up and I'm not sure what to get him. We've been together for over a year now. (15 months) and we've already given eachother promise rings, I've given him a watch, video games, books, a lighter, and I'm running out of ideas. He plays sports but doesn't follow any teams, he plays drums, and he loves snowboarding. I really want to get him a good present so any ideas are much appreciated !!
