Blue boater

The Blue boater is a piece of members only headwear. There are no requirements for wearing this boater and they do not confer combat bonuses upon the player. To obtain a blue boater, the player can either trade with another player or receive one as a Level 2 Treasure Trail reward. The blue boater can be stored in the Costume room of a player-owned house.

When the graphical update came to Runescape (the update bringing in HD), there is a glitch that makes it look like it has a red ring instead of a blue. It still appears blue in the inventory and is called a blue boater.
