My players have suggested that they wear two utility belts strung across their shoulders and one around their waist, adding three to their encumberance rating. I feel that this is a bit ... I'm not sure, but it doesn't sit right with me; it smacks of exploiting the rule. They already have a backpack and so are suggesting that they can add 7 to their normal value.
Have any of you come across this idea and what did you say in response if so?
