Runecrafter hat (yellow, goggles on)

The yellow runecrafter hat can be bought at the Runecrafting Guild for 1,000 Runecrafting guild tokens. The goggles can be toggled off by right-clicking the item and selecting "goggles", resulting in a different hat.

While wearing the goggles of the hat on one's face, their straps will match the colour of the wearer's hair.
