Abstract: A tool kit vest assembly securely holds and provides easy access to tools, allows for adjustment of the vest, and provides ventilation to dissipate heat. The assembly includes a flexible panel having a first end and a second end. An aperture is positioned in the panel between the first end and the second end and between a pair of lateral sides of the panel. A dorsal portion of the panel extends from the aperture to the first end of the panel. A pocket is coupled to the panel. A flap is coupled to the pocket and is positionable between an opened position and a closed position. An interior fastener couples the flap to the pocket when the flap is in the closed position. An exterior fastener couples the flap to the panel when the flap is in the opened position.
