That guy who has everything? He doesn’t have this stuff
So you’re trying to buy a gift for that guy. The guy who seems to have every piece of gear known to man… and a few more for good measure. The guy who you (and all of your friends) agree is first one you’ll go to in the event of a zombie uprising / nuclear holocaust.
We know that guy. So we carry some stuff that we know he’ll love, and that we’re pretty sure he doesn’t already have.
