The Robin hood hat is a Ranged hat that requires level 40 Defence to wear and can be obtained by completing level 3 Treasure Trails, or from other players.
For 1000 Loyalty points, players can buy the option to change the colour of robin hood hats. The colours are red, blue, yellow, and white. This cannot be refunded, but once bought, players can change the colours of their hat as many times as they like. A coloured Robin hood hat is not tradeable, but a player can use their hat on Xuan to change it back to green, and thus making it tradeable again.
When the Item Lending feature was first released, there existed a glitch in which players could lend out the hat under "Until logout", wait until the player equipped the Robin Hood Hat, and then logout. This would result in the victim becoming bald.
With the Loyalty Programme update of 28 June2011, the street price skyrocketed because of the multiple colours made available, with some players selling these hats as high as 15 Million GP upon hearing of the update. Approximately 24 hours later they were still being sold for between 8 Million and 15 Million GP, but about a week later prices slowly returned to normal.
When the player hovers over the robin hood hat option in the loyalty points shop, the message "Robin Hoods' amazing technicoloured dream hat!" appears. This is a reference to the musical Joseph and the Amazing Technicolor Dreamcoat.
