History of Kairos Function Vest

Overview

The Kairos Function Vest is Legendary Chest Armor for Hunters and one of the pieces of the Kairos Function Suit, a Legendary armor set from Destiny 2: Curse of Osiris with versions for Hunter, Titan and Warlock. The set's lore is written as research on the Vex.

The vest's flavor text reads: "Multiple analyses confirm: the milky radiolarian fluid found in Vex chassis is organic in nature." —Sister Faora, "Theories on the Vex"

Acquisition

Xûr sells the vest. The set can also be earned through rank-up packages from Brother Vance, and it is not a loot drop. Xûr's stock rotates, so the vest is only available when it appears in his inventory.
