We try to create as much distance as possible between your back and the bag, separating it from your clothing to prevent uncomfortable perspiration and maximize airflow. You can do this using stretched net, a technique that has been around a very long time, foam squares or various other devices. You can also do the opposite and try block the flow of airflow by creating an absorbent pad.
How can you measure and calibrate the level of discomfort, using a standardized, repeatable test? This is what our Air Cooling technology seeks to achieve and deliver.
All our Air Cooling certified bags undergo a series of tests, carried out on a mannequin that is specially designed by our teams. This mannequin, which is fitted with several input and output sensors to simulate air flow, has the advantage of being constantly available, can be accurately assessed and, unlike testers in the field, can't voice feelings or opinions.So it's always in the same mood and remains objective even if we ask it to repeat the same thing 100 times😉.
This may all sound easy but the real difficulty resides in establishing test protocols. You have to follow a set of procedures for air flow, humidity levels and adhere to very strict standards; this involves developing new technology as in order to assert the merits of a system to customers and the DGCCRF, you have to be able to prove that it follows a well-established methodology.
