Sunglasses

Sunglasses are a vanity item equipped in the Social Helmet slot, and can be worn without losing set-bonuses from your armor (except for afterimages). Sunglasses will only change the appearance of your character as well as the Sun by giving it a pair of sunglasses too. Only players with sunglasses will see the Sun with sunglasses, so if any player equips them in multiplayer, other players without sunglasses will not be affected. The effect will work even if the item is equipped in the social slot.

Sunglasses do not offer any bonus stats to your character. Like Goggles, these do not cover the player's hair, allowing you to hide your helmet to show your hair.

Trivia
