Zoey's smart muscle suit. Underneath her standard issue uniform, she wears a partial muscle suit, which reinforces her torso, abdomen and waist, while open in the back for easier heat release. The leggings are also part of the suit, reinforcing her knees, calves, shins and ankles and conducing the heat towards her thighs, facilitating the heat exchange.

This is necessary due to her physiognomy, where her body produces more heat and tends to overheat. This is due to an enzyme that interacts with adrenaline, increasing the acidic factor of their blood. Prolonged overheating will result in internal bleeding and could result in systemic organ failure. Zack shares this trait and is actually worse with him as he has lower stamina.

Fun fact: January 6th is her birthday.
