Here is the Rotu tribe Buff (blue) from the 4th season of Survivor - "Marquesas" which aired in early 2002. This season was filmed in Marquesas and featured 16 contestants split into 2 tribes "Rotu" and "Maraamu", this season the contestants had to source their own food as none was given to them.
The original tribe consisted of Gabriel, John, Zoe, Tammy, Robert, Paschal, Kathy and Neleh. Rotu were a strong force to reckoned with, the Rotu tribe won 2 Reward challenges and 5 Immunity challenges prior to the merge. All the contestants who made the merge were once part of the Rotu tribe at some point in the game.
This buff is a Reebok version and was released when the season aired, the black "survivor" logo buffs are harder to find.
