The TranStrap is a BYO transit strap made out of heavy-duty materials designed to withstand hard commuting on public transit. The idea is that instead of clutching the public straps on your local mass-transit vehicle, thus exposing yourself to DNA, cooties, and clammy-palm sweat residue, you bring your own and ride in quiet assurance that your hand is only coming into contact with your own dried commuter-juices. They also make a sling to allow you to hold a book while still giving you something to hold onto while the vehicle jumps and judders.
