Arguably the most overlooked piece of climbing gear is the harness. It's a lot more than just some polyester and foam slopped together that keeps you attached to the wall. A good harness can take a hanging belay from a painful, leg-numbing experience to a comfortable, proverbial walk in the park. You do know that you probably shouldn't wear a rock climbing harness to the park right? That would be kind of weird. Stick to the rocks, you'll fit in with the trad and sport climbing communities a lot better anyway.
