Stealth Attire

The Stealth Set is an Armor Set in.

Location and Uses
The Stealth Set is an Armor set consisting of the Stealth Mask, Stealth Chest Guard, and Stealth Tights. Each piece of the Ancient Armor set can be purchased at the BotW: armor shop in Kakariko Village.

The Sheikah designed this armor for stealth purposes, so each piece of the Stealth Armor set provides the Stealth Up effect. Wearing the entire set while every piece is upgraded at least twice provides the Night Speed Up set bonus, which increases Link's movement speed during nighttime hours. These bonuses all have one major drawback however: each piece has lower defense than other forms of armor.

Trivia
Early concept art showed the stealth set was intended to look like the garb seen on all Sheikah NPCs, however this was likely changed because in-game canon states that only sheikah can wear them, not hylians or anyone else.

Sheik's new redesign has her wearing the Stealth set.
