Most climbing gear should be selected for function rather than looks. First and foremost, it has to do the job. Sometimes that job is saving your life under severe conditions so smart climbers buy the gear that will let them do what they want to do easily and safely, regardless of what it looks like. Chalk bags are the one exception to this rule. All they have to do is hold climbing chalk. It's not difficult.
