The farmer's outfit is a bonus experience set obtained from Treasure Hunter or as a reward from Cabbage Facepunch Bonanza for 800 renown a piece.
From 9 to 12 May 2014, it was possible to make the farmer's outfit by combining magic beans and either discarded sacks, leather scraps, torn cloth, tattered cloth, or handful of straw. 1,100 beans were needed for the whole set.
Each item of the set gives a Farming experience bonus of 1%; when all of the pieces of this set are worn, they provide a total of 6% bonus.
If lost on death, the outfit can be retrieved from Diango in Draynor Village at no cost.
