The clothes pouch is an item which needs to be attached to the Forestry kit or basket (irreversible process) that then allows the player to store the lumberjack or Forestry outfit in order to receive the outfit's benefits without having to wear them. The upgraded Forestry kit must be equipped or in the player's inventory to receive the bonus. Equipping any piece of other outfits in the hat, body, legs, or boot slots which would be part of a set effect bonus, such as various skilling outfits (including the Graceful outfit), Barrows sets, or inquisitor's armour, will disable the lumberjack effect for those slots.[1][2]
They can be created by using a piece of leather on the clothes pouch blueprint with a thread in the inventory. Doing so requires level 50 Woodcutting and Crafting, and the blueprint is consumed in the process. When the clothes pouch is attached to the Forestry kit, the kit does not change any interface options.
While the clothes pouch item itself has a weight of 1kg, when attached to the Forestry kit and with an outfit stored, the Forestry kit whilst worn has a weight of 0kg.
