The Briefsafe is the most disgusting way to keep your valuables secure. The tightie-whities have nasty brown stains on the posterior region, and a hidden 4x10-inch velcro pocket in the fly for your passport and stash of cash. You can use the Briefsafe at home or on the road–even serious criminals will probably hesitate before plunging their hands into skid-stained underwear. The Website that sells these skivvies (at about $10 a pop) also has a range of other innovative “diversion devices” like hidden wall outlets and fake-bottomed Kibbles cans, just in time for your summer security needs.
