Bunker Supply developed their ACCLIMATE body cooling system under Project Warcry in conjunction with Airman Innovator Capt Justin O’Brien.

Project Warcry is their DoD-wide program that takes end-user ideas and accelerates the product development cycle and deployment of ideas by way of the Bunker Supply team’s expertise in engineering and manufacturing.

Heat injuries have resulted in at least 17 service member fatalities and costing over $1 billion from 2008 to 2019, particularly affecting recruit trainees and combat specific occupations. ACCLIMATE provides an active cooling solution that enhances warfighter performance and reduces heat-related injuries in extreme environments. ACCLIMATE provides these advantages in combatting heat injuries:

Decrease Temp By 32°F
Built to endure the demands of a full shift, increasing safety and endurance. In-field testing demonstrated an average internal vest temperature drop from 87.75°F to 55.75°F.

Up To 12 Hours Of Cooling
Built to endure the demands of a full shift, increasing safety and endurance.

This powered system does this through a cooling pad at the back as well as a 3-liter reservoir containing water which is chilled before being returned to the cooling pad.

The system can be worn as a backpack or integrated into body armor. Currently available in Coyote, an OCP version will be offered in early 2025.
