The set of Lumberjack clothing is dropped in pieces by Undead Lumberjacks in the Temple Trekking activity. Lumberjack clothing, when worn, gives extra Woodcutting experience for cutting logs. This includes experience gained from chopping ivy. However, this does not include experience from the Distraction and Diversion, Evil Tree. Level 44 Woodcutting is required to wear Lumberjack clothing
Lumberjack clothing is obtained during the Temple Trekking/Burg De Rott ramble activity. One of the events players may encounter during Temple Trekking is an area where there is a broken bridge. This event is where the clothing can be obtained. In this event, undead lumberjacks may come out of the water (note, sometimes no lumberjacks appear and trees must instead be used to repair the bridge). They drop planks, which can be used to repair the bridge, but they can also occasionally drop pieces of the Lumberjack set. Only one piece can be obtained per event, and only three undead lumberjacks will appear. After the 17 August 2011 revamp, the undead lumberjacks will drop the pieces in order, starting with the boots, then the hat, legs, and top. Missing pieces will be dropped before you get duplicates of the set. The pieces also became far more common drops after this update. All of the Lumberjack items can be obtained on any of the routes. The pieces are dropped in a cycle and additional sets can be obtained once you have completed one.
The fastest way to obtain a set of Lumberjack clothing involves taking any person through Route One (the easiest route). This enables the player to skip past most combat events. In addition, the player should carry Slayer rings or Kharyrll Teleport runes to teleport out of the Bog event, and possibly also the sick people event, due to the time these events take. At higher levels, the person the player guides through the swamps is able to tell what lies ahead, making finding the broken bridge events much easier. Rolayne Twickit has an advantage of being able to run ahead at only level 20, whereas the other NPCs only gain this ability after their third level tier.
The usefulness of the Lumberjack clothing is highly debated. Depending on the goal the woodcutter is aiming for, generally, the difficulty in obtaining all four pieces outweighs the benefits. Assuming the goal is from level 44 to 99 (roughly 13,000,000 experience points), 2.5% roughly works out to 325,000 experience. With an estimated 80,000 experience per hour by chopping ivy, the Lumberjack clothing can only save four hours of woodcutting. However, the chance of obtaining a full set of Lumberjack clothing in four hours is low. Some players have reported only obtaining the full set after 10 hours of play, though this may no longer be the case. Hence, some players regard the lumberjack clothing as worthwhile only for aesthetic purposes, unless the goal is to gain very high Woodcutting experience (for example, 200,000,000). However, the above analysis mainly applies to players who are only interested in gaining Woodcutting experience. Some players regard Temple Trekking as a fun and rewarding activity in itself, in which case getting a set of Lumberjack clothing is seen as a bonus. Some other players find training Woodcutting to be tedious, so acquiring Lumberjack clothing helps them gain Woodcutting experience on the occasions where they need to train it (such as leveling up to qualify for a quest).
