What is the main purpose of a survival vest?

The main purpose of a survival vest is to hold survival gear for emergency situations post-ejection or ditching. These vests are specifically designed to enhance the chances of survival by providing immediate access to essential equipment needed in case an aircrew member needs to eject from an aircraft or experiences a water landing. The survival gear typically includes items such as a first aid kit, signaling devices, emergency rations, and other tools that can assist in navigation, communication, and self-rescue.

In emergency situations, quick access to these survival resources is critical, and the vest is designed to be worn comfortably over flight suits, ensuring that the gear is readily available without hindering movement. This functionality makes the survival vest a vital component of an aircrew member's flight gear, preparing them for unforeseen emergencies.
