The hardleather body is low-level Ranged armour. It may be equipped in the torso slot by players with 1 Ranged and 10 Defence. It provides better protection from melee, magic, and ranged attacks than the leather body and grants a modest boost to one's ranged accuracy.
Players may craft a hardleather body with 28 Crafting. This requires a piece of hard leather, a needle, and thread, and grants 35 Crafting experience. Crafting hardleather bodies can give 80k xp/hr, and is relatively cheap compared to other methods. Many players choose to use this method for precisely these reasons.
A hardleather body can be required for easy and medium clues.
"Wave along the south fence of the Lumber Yard. Equip a hard leather body, leather chaps and a bronze axe."
"Cry in the Catherby Ranging shop. Bow before you talk to me. Equip blue gnome boots, a hard leather body and an unblessed silver sickle."
