Best Gift Idea for the Outdoors Lover in your Life?

So what's the best gift idea for the outdoors lover in your life? My pick would be a headlamp. They are inexpensive and can be used in anything from backwoods camping, to a handy tool when the power goes out at home (I've used mine to fix the car in the dark and have one in the glove box for a roadside emergency). This Black Diamond headlamp was found at my local outdoors store Wild Rock for only $19.99 and it includes Batteries! Have a larger budget? There are plenty of models to choose from all with different features.
